New Professors 2012
Nguyen Tien Son, professor in Semiconductor Materials,
received his PhD in solid state physics at the Department of
Physics and Astronomy, University of Amsterdam in 1993.
After that he worked as a postdoctoral fellow (1993-1997)
at the division of Semiconductor Materials, IFM, Linköping
University. He became docent (1999) and associate professor
(2003) in materials science at IFM.
His research covers from the fundamental properties of
semiconductors to the physics of defects and the influence of
defects on the material properties. The materials of interest include bulk Si, SiC, GaN, AlN, and ZnO as well as the thin-film
structures of III-nitride alloys. In the research, different optical,
electrical and magnetic experimental techniques, such as photoluminescence, deep level transient spectroscopy, magnetic
and cyclotron resonance, have been employed.
His current research interests focus on defect physics and
defect engineering in SiC and III-nitrides (GaN, AlGaN and
AlN) to solve material problems for their applications in highpower and high-frequency electronics and deep-ultraviolet
light-emitting devices.
Sergei Simak Doctor of Physical and Mathematical Sciences
(2000) at National University of Science and Technology (MISiS), Moscow, Russia. Forskarassistent at The Department of
Applied Physics, Chalmers University of Technology and Göteborg University, Gothenburg, Sweden 2000-2002, Forskare
at The Department of Physics, Uppsala University, Sweden
(2002-2004), University lecturer at IFM, Linköping University
since 2004.
Sergei’s research is focused on studies of physical properties of materials based on fundamental laws of Nature, first of
all the principles of Quantum Mechanics. What he does, can
be described as “theoretical experiments” employing modern
supercomputers instead of standard experimental equipment.
He develops new methods which allow one to calculate and
predict physical properties of solid materials at given external
conditions, such as, for example, pressure, temperature and
composition. In particular, he is deeply involved in studies of
8
the Earth’s core and superhard materials. The results of his
research are presented in many publications, in particular in
high-impact journals Science, The Physical Review Letters and
Proceedings of the National Academy of Science of the USA
(PNAS).
Sergei’s main current interest is in the materials for fuel
cells, i.e. the possible future sources of “green” energy which
do not pollute the environment. His ultimate goal is theoretical
materials design of fuel cells with optimum properties. This
work brought substantial attention of the international scientific community. In particular, Sergei got a patent for the solid
oxide fuel cell electrolyte, designed exclusively on the basis of
quantum mechanical calculations. Excellent properties of the
predicted material were later confirmed by experimentalists in
Florida University, USA.
The results of Sergei’s research have been many times described in popular form by different scientific sources (like in
“A Clean Air Act At the Quantum Scale” by Phil Schewe, James
Riordon, and Ben Stein, Physics News Update, Number 607
#1, October 2, 2002; “The quantum origin of oxygen storage”,
Physics Update, Physics Today, December 2002; “Quantum
oxygen storage” by Ed Gerstner, Nature Materials Update, 10
October 2002); by the Swedish Radio (like the presentation by
the Swedish Radio P1, 2007-06-29); and by newspapers (like
in N. Olauson, “Jordens innersta hemlighet avslöjad”, Newspaper Östgöta Correspondenten, 2007-06-29; C.-J. Bilkenroth,
“Svenskar först till mitten”, Newspaper Svenska Dagbladet 2007-06-29; “Stärkt teori om jordens kärna”, Dagens Nyheter
nätupplaga DN.se, 2007-06-29; “Nya rön om jordens inre”,
Norrköpings Tidningar NT.se, 2007-06-30).
Sergei’s scientific interests would be incomplete without
teaching. He is a teacher and developer of undergraduate
and Ph.D. courses. In particular, he gives regular courses in
Solid State Physics and Relativistic Quantum Mechanics at
Linköping University. His international PhD courses “Quantum Simulation of Liquids and Solids” hosted by Centre européen de calcul atomique et moléculaire (CECAM) were great
success and attracted young researchers from all over Europe.
He has also been principal supervisor of 2 Ph.D students (both
received the Ph.D. degree), 4 M. Sc. Students, and 2 Post. Docs.
Legislation
IFM has an injunction, according to the Swedish Environmental Code, to submit a yearly report to the local environmental
agency describing the laboratory work at the department. The
agency makes regular inspections at IFM.
Environmental management systems
The Rector at LiU decided in 2006 that all departments must
work according to an environmental management system.
Since 2009 a regulation of environmental management for
government agencies stipulates how to perform the environmental work. In 2010 an environmental enquiry was performed at LiU and resulted in several environmental target
areas and goals.
At IFM a plan for the environmental work was first established in 2004 and resulted in measures taken towards reaching an environmental management system. An environmental
plan for 2011-2012 was decided by the IFM board in March 2011
and consists of an action plan with environmental targets and
measures needed to be taken. The environmental work has
been presented in the local co-operation group during the year.
IFMs environmental targets 2011-2012
The targets are organised according to the long-term environmental areas adopted by LiU and IFM and are to be accomplished by 2012-12-31.
Limit the contribution to the climate changes
1. Decrease the energy consumption of IT-equipment by installing energy-saving mode and increasing the number of
switched off equipment.
A system for automatic measurements of the number of
computers turned on or off was to be developed and implemented during 2012, but unfortunately it proved to be
difficult to find a method that provided reliable data. When
installing computers in offices etc, the computer support
group always configures to energy-save mode. The measures
to achieve the target were partly fulfilled.
2. Work shall be performed to take the previously designed
measures to reduce the environmental impact from travel
made by IFM.
Information to the IFM employees regarding the guidelines
for environmentally friendly travelling set by LiU is needed
during 2013. During 2012 it became possible to use the LiUcard when travelling with the Campus bus. The measures to
achieve the target were partly fulfilled.
Limit the contribution to the climate changes/ efficient
use of natural resources
Organization
The Environment
3. IFM shall, whenever possible, buy computers with good
environmental performance (use of electricity and content
of hazardous substances) based on the demands in procurements of local/public framework agreements.
IFM follows the available framework agreement. The measures to achieve the target were fulfilled.
Efficient use of natural resources
4. IFM shall supplement the waste sorting system in accordance with decisions made by LiU regarding waste sorting.
The waste sorting system has been supplemented during 2011 and 2012; the measures to achieve the target were
fulfilled.
Minimal impact from use of hazardous or contagious
substances
5. IFM shall implement future guidelines for handling of hazardous waste and other laboratory waste at LiU.
IFM has decided to offer some of the most common containers for laboratory waste for free. Information regarding this
and the new routine for laboratory waste has been sent by
e-mail and published at the IFM website. Information has
also been given at different meetings during 2012. At IFM,
the laboratories have embraced the new routines to a large
extent. Information about the new routine for handling hazardous waste was given by e-mail and information at different meetings. The routine was published on the IFM website.
The measures to achieve the target were partly fulfilled.
6. Risk assessments shall be made before all new experiments/
laboratory work and when purchasing new equipment.
In the autumn 2012 LiU initiated work to improve information on the website, templates etc. When that work is completed, spring 2013, IFM employees will receive information
about risk assessment. The measures to achieve the target
were partly fulfilled.
Organizational action
7. At IFM all laboratories where work that can be considered
riskful takes place, must have an appointed person responsible for supervision of the laboratory.
Improvement is needed to make sure persons responsible
for supervision of laboratories have a written delegation.
Information was given at different meetings during 2012 and
the work will continue during 2013. Laboratories at IFM have,
to a large extent, a notice outside the entrance with contact
information. The measures to achieve the target were partly
fulfilled.

School contacts
Our department has always been very active in different
forms of school contacts. For several years we have had young
researchers part time employed for external contacts, one each
from physics, chemistry and biology. IFM is represented in the
board for school contacts of LiTH. The goal of this board is to
coordinate and support existing activities, as well as developing
new exciting activities.
Perhaps the most frequent activity is various study visits
by children, young people and teachers. In May we have a
popular activity directed to secondary and upper secondary
school teachers, the May Mingle, Majminglingen. Schoolteachers and university teachers meet in lectures and discussions.
This activity is arranged in cooperation with the Mathematics
department.
Open house days
Linköping University arrange yearly two open house days for
schoolteachers and pupils, and IFM participated with hands-on
exhibitions during these days.
Quintek
IFM received about one hundred female high-school students
within the Quintek program, aimed to promote the interest
for science and technology among the young women. At this
event have the high-school students a chance to familiarize
themselves with university studies though meeting university
teachers, PhD-students and MSc-students from IFM in activities such as mini lectures, science demonstrations and general
discussions.
Popular science week
In October we participated in a Popular Science week for the
general public. This event was initiated by the Professor Per
Jensen in 2005, and the interest is growing. The success of
the initial Popular Science day has led to a larger three-day arrangement in cooperation with other departments, the Popular
Science week. IFM participated with various exhibitions and
lectures.
Senior researchers and PhD students from the
Semiconductor materials Division shared their
excitement about science and research with the
pupils from Katedralskolan. In an introductory
lecture by Vanya Darakchieva and Olle Kordina, the
youngsters learned about the properties and societal
impact of group-III nitrides, graphene and SiC. The
young people also visited key labs and witnessed
growth runs and exciting experiments on materials
characterization.

The nominal time for the Engineering M.Sc. programs is 5
years. The first three years mainly consist of compulsory courses in basic subjects and corresponds to B.Sc. degree. During
the third year the students make a choice among the different
specialisations (profiles) in years 4-5, which contain some compulsory courses (profile courses) but most are selectable and
can be composed to fit the students own interest.
The Y(Yi)-students can choose between 11 profiles, two of which
are related to our division:
• Theory, modelling and visualization (Irina Yakimenko)
• Material and nano physics (Jens Birch)
In addition, we also give physics courses on the Programme
in Physics and Nanoscience (FyN), leading to a Bachelor of
Science (3 years) with a major in Physics, and on the Master’s
Programmes in Physics and Nanoscience (MFYS), Materials
Physics and Nanotechnology (MPN), and Biomedical Engineering (BME).

Most of the chemistry courses offered are part of the three-year
programmes, Chemistry (Ke) and Chemical Biology (KB), (180
credits points/hp). Students completing these programmes
are awarded the degree of Bachelor of Science in Chemistry.
All courses within the Chemistry Program are also available as
separate courses.
The program, Chemical Biology (KB), have an open entrance
for the students: after a year of studies the students can choose
to continue in natural science (or to choose a more technical
variant to become engineers. Chemical Biology combines understanding of complex biological processes with the fundamental principles of chemistry.
During 2009 all study programs were transformed into
three-year Bachelor of Science programs (180 hp) and master
programs on advanced level for further two years (120hp).
Chemistry offers master profiles in Organic Synthesis/Medicinal Chemistry and Protein Science.
Some of the chemistry courses are also included in the study
programmes of students majoring in Biology and in Teacher
Training Programs (students becoming Upper Secondary
School teachers). Biology bachelors are required to earn 21 hp
chemistry, while Science Education majors earn up to 60-120
hp of chemistry. Introductory courses in chemistry for the
study program Medicinal Biology were started under the
autumn semester.
Besides the above mentioned courses as part of the Mathematical Natural Science, chemistry courses are offered for engineering students in the M.Sc. program Chemical Biology (also
mentioned above) and Engineering Biology (TB) (270 hp).
The Chemical Analysis Engineering (KA) (180 hp), a threeyear programme, has analytical chemistry as the main profile.
Basic Year (130 students, 13 hp), with introductory courses in
Chemistry on a secondary school level, is offered to students
who do not meet the requirements for studies at the University.
Final theses, the last 30/45 or 60 hp in the Chemistry and
Chemical Biology program, have been carried out by six students. For the engineering programs 14 KA students carried
out the 16 hp, and 14 KB students the 30 hp final theses work in
the chemistry area. Besides projects conducted on campus or
at the University Hospital, were projects performed at different
national companies and at University of Sidney.
Under the period 10 students were awarded the Master of Science degree and 17 students the Bachelor of Science from the
Chemistry and Chemical Biology programs. From the Chemical Analysis Engineering program were 17 awarded the degree
Bachelor of Science in Chemical Analysis Engineering and
15 Chemical Biology engineering students were awarded the
M.Sc. degree.
Altogether approximately 600 students have enrolled in about
60 courses in chemistry through the year 2012.

Applied Ethology and Animal Biology
This program deals with animal behaviour and biology from
an applications perspective. Central issues are the biology of
stress and animal welfare, domestication effects on behaviour,
physiology of behaviour and conservation biology.
The programme is taught in association with Kolmården
Zoo which sometimes is the teaching venue. Learning rests on
a mix of classroom lectures, seminars and hands-on projects
involving studies of animals in captive environments. All over
the world, problems associated with keeping animals in captivity require increased attention and knowledge.
After completed studies, the student should be well-acquainted with theories of animal behaviour and biology, and have a
close understanding of the concepts of animal welfare and conservation. Examination requires the ability to plan, implement
and present a scientific investigation in the subject framework
of the programme.

Master’s Programme in Molecular Genetics and
Physiology, 120 ects
This master’s programme focuses on eukaryotic molecular
genetics and physiology, with particular emphasis on how this
relates to both embryonic development and adult homeostasis.
The programme is divided into a first year of courses and
a second year of work on a particular research project in a
laboratory setting. The courses are taught using a multitude of
formats, including regular lectures, practical laboratories and
seminar discussions.
The laboratory classes will utilize powerful biological model
systems such as Arabidopsis or chicken to illustrate modern
concepts of molecular genetics and physiology. The thesis project during the second year (diploma work) will be conducted
in a research laboratory at LiU or other university, in industry
or the public sector.
During the first and second year, there will be a parallel
seminar course in Current Concepts in Life Sciences, involving research articles and research lectures by invited speakers.
During the second year, a parallel course in thesis writing and
presentation techniques will be given.
Master’s Programme in Ecology and the
Environment, 120 ects
Students will develop a critical scientific approach to ecology and an awareness of its role in society. The programme
includes training in skills in experimental design and ecological field methodology, both in the classroom and during the
individual project in the second year which can be linked to
current research projects at the department – e.g. in grassland
and weed ecology, ecology and Biogeochemistry of shallow
waters or conservation biology. Alternatively the link can be to
other universities or research institutes.
This master’s programme also emphasizes the need for, and
use of, mathematical models and statistical analyses for addressing complex ecological problems. Such methods serve as
Master´s Programme in Physics and Nanotechnology
Aim and Organisation: The Master’s Programme in Materials
Physics and Nanotechnology educates specialists in the area of
physics of novel materials. The master students are prepared
for university or industry careers in materials related research
and development.
The programme covers a wide range of materials including
materials used in semiconductor and nano-technology, optoelectronics, biotechnical applications (biocompatibility), chemical and bio-sensors, mechanical applications such as hardness
and elasticity etc.
The programme comprises four semesters. The first autumn
semester consists to a larger part of compulsory courses while
the two following semesters contains mainly elective courses.
The fourth semester is assigned to the Master’s thesis project.
The student can chose courses among essentially four elective profiles:
•
•
•
•
Electronic Materials and Devices
Surface and Nano Sciences
Organic Electronics and Sensors
The master’s thesis should be based on high quality scientific
research within the area of the profile chosen by the student.
This work can be performed either at Linköping University or
at other universities.
Information about this master’s programme can be found
on the web page: http://www.liu.se/en/education/master/
programmes/6MMPN?l=en
Progress
The programme started in 1996 and around ten students have
since then joined the programme each year. This year when
tuition fees were introduced the number dropped so only five
students entered the programme. The study results of our International master’s students have overall been good. Several of
them have produced very good results and have after receiving
their MSci degree continued to a PhD degree at LiTH, KTH,
CTH, LTH, KU and at universities abroad.

International Master’s
Programmes
powerful tools to e.g. identify crop management strategies for
effective biological control, understand life-history strategies
and the risk of population extinction in a variable environment,
or evaluate the preservation status of nature reserves and the
impact of management schemes.
The courses cover theories in population, community and
systems ecology and how they relate to current environmental
problems. Examples are methods in ecology, mathematical
modelling of biological systems and conservation biology.

IFM is the host for the doctoral programme Forum
Scientium (www.liu.se/scientium).
Forum Scientium is a multidisciplinary programme and the
doctoral students have backgrounds within biology, chemistry,
medicine, physics and technology. The research projects are located at two faculties, Faculty of Health Science and the Faculty
of Science and Engineering. Forum Scientium has financial
support from the faculty, from the supervisors and from the
Swedish Research Council.
The strategic objectives are “PhDs well prepared for their
future careers through a structured doctoral programme which
includes research of world class, and cooperation and multifaceted contacts with industry and society”.
During 2012, the doctoral programme Forum Scientium
had around 60 PhD-students, and 8 PhD-dissertations were
defended.
Since 2008, a special Forum Scientium Award exists. Forum
Scientium PhDs can apply for an award providing 50% of the
salary for a period of up to one year from the PhD-exam. The
award aim at promoting the future career for the awardees, and
to promote twinning among active Forum Scientium members. Most important is also that they should be of benefit for
the active PhD-students. The awardees are called “Transformers” and during 2012 we had all together five transformers.

Agora Materiae is a Graduate School for PhD students working
in the research field of novel functional materials. The Agora
Materiae Graduate School is dedicated to offer graduate studies
in a true multi-disciplinary environment. Agora was started up
in the beginning of 2012 and has got 40 members during its
first year. Agora Materiae is hosted by IFM, but attracts PhD
students from several departments such as ITN and IEI. Agora
has financial support from AFM, which manages larger investments in research and infrastructure, based on the strategic
support from the Swedish government for materials-science.
The PhD students can work in an environment, at the
forefront within several research fields within materials science
and the students are offered breadth and depth in scientific and
didactic competence. A student council with five or six PhD
students in the Agora graduate school acts as contact between
the Agora members and the management of the graduate
school. The student council is responsible for activities e.g.
study visits, the home page, symposia and a summer conference.
Some important activities within the Agora Materiae Graduate
School are:
• Seminar activity. Every fourth week, there is a joint PhD students seminar activity. Also invited speakers, often former
PhD students, give seminars at these occasions.
• Common courses. Agora Materiae graduate school will arrange common courses. Can also be compulsory courses for
the graduate school.
• Study visits: There are visits to research-intensive companies
and/or academic departments arranged. Also study visits
outside Sweden will take place.
• Summer conference: Every year, there will be a summer
conference during approximately three days arranged, with
activities like invited presentations, poster sessions,
• Progress reports. Together with the individual study plan,
the progress plans three times a year are a follow-up of the
progress in the PhD-students projects, planning of their
research work with the purpose to improve the communication between the PhD-students and their supervisors. • Yearly individual follow-up. Each PhD student in Agora will
have a discussion with the graduate school director to discuss project, progress, time schedule, but also problems in
the graduate program.
IFM Graduate Programme
Per Olof Holtz, Director of Graduate Studies
The graduate program at IFM, Linköping University aims at
a degree of Licentiate or Doctor of Technology or Philosophy
for the PhD students. The requirements for the Licentiate /
PhD exam consist of a course part, corresponding to 30/45 and
60/90 credit points (hp), and a doctoral/licentiate thesis. The
nominal time for training to the Doctor degree is four years
(full-time training) and for the Licentiate degree approximately
half the time. The PhD students are encouraged to do teaching
at undergraduate level (at maximum 20% of their time), which
means that the total time to provide the Doctor degree can be
up to five years. During the year 2012, 38 new students entered
the graduate program at IFM with PhD as the final exam and 3
new students started the graduate program with the licentiate
exam as the final exam. For a development of the number of
students entering the graduate program at IFM during the last
five years, see Diagram 1 below.

The course menu is organized jointly for the different scientific
research groups at IFM, which means that a broad course
menu within physics, chemistry and biology is offered,
reflecting the strong inter-disciplinary character of IFM.
During the academic year 2011/12, the PhD students could
choose between approximately 60 courses at IFM. The
students can also follow courses given at the graduate schools
Agora Materiae and Forum Scientium at IFM, at other departments of Linköping University or at other universities. For all
PhD students, who do teaching at undergraduate level, a basic
pedagogics course is compulsory. IFM is arranging a specific
pedagogics course for PhD students registered at the department. A course in science methodology and ethics is compulsory for all PhD students.
At IFM, a doctoral-studies board is a forum for various topics associated with the graduate studies. This council, with four
meetings per year, has the following members: The Director
of Graduate Studies, one representative for each scientific research area at IFM and two PhD student representatives from
Physics and Chemistry/Biology, respectively.
Each graduate student has to make up an individual study
plan each year. This study plan should contain a time schedule for the PhD studies, a project plan for the research work
together with teaching and other duties at the department. This
individual study plan is followed up each year.

care solutions and an important contribution from LiU to the
regional Vinnova supported program “New Tools for Health”.
The missions of LIST are to stimulate the interest for and
increase the possibilities to perform excellent research on new
technologies for distributed health care at LiU and to reinforce
the importance of long-term collaboration between faculties
in this research area. The Scientific branch of Applied Physics
is engaged in LIST through Karin Enander (part time director), Anke Suska (part time co-director), Ingemar Lundström
(chairperson of the steering committee) and Anthony Turner
(member of the steering committee).
LIST activities include support of research projects (in total
1 MSEK/year) and arrangement of workshops. In 2012, LIST
granted financial support to the following projects:
• “Optically coupled touch screens for lab-on-a-chip medical
diagnostics”; PI: Daniel Filippini (IFM).
• “Behavior analysis in elderly HF patients”; PIs: Pierangelo
Dell’Acqua (ITN) and Tiny Jaarsma (ISV).
• “Wearable contact lens biosensors with nanoengineered architecture at interface”; PIs: Martin Mak and Ashutosh Tiwari

Natural photonic structures Optical properties of cuticles of several beetles were studied to learn how nature has
designed biomultilayers. Figure 1 show a specimen of Chrysina gloriosa viewed through a left-polarizing (LPC) and rightpolarizing (RPC) filter (Arwin, Fernandéz, Järrendahl, Landin,
Magnusson).
The polarization properties of three specimens of Cotinis
mutabilis with different color were studied by analyzing the
Mueller matrix data and complemented with the structure
revealed by microscopy techniques (Muñoz, Mendoza, Arwin,
Järrendahl).
BRDF measurements and Mueller-matrix ellipsometry on
Cyphochchilus insulans was performed to analyze scattering and
depolarization properties (Åkerlind, Hallberg, Arwin, Järrendahl).
Figure 1 Chrysina gloriosa viewed through a left-polarizing (LPC) and rightpolarizing (RPC) filter.
Artificial photonic structures Gold-silica dot arrays were
investigated in collaboration with M. Käll and a model describing their optical response was developed. Figure 2 show
transmission data from this kind of structure (Mendoza,
Järrendahl, Arwin). Nanostructured helical films composed of
InAlN nanorods were fabricated and analyzed in collaboration
with J. Birch at LiU. Left-handed and right-handed structures
were grown. In collaboration with École Polytechnique in Paris
imaging Mueller-matrix analysis was performed (Magnusson,
Arwin, Järrendahl).

Electrochromic thin films Tungsten doped NiO films with
different compositions were characterized by ellipsometry.
Dielectric functions of nickel doped WO3 were studied in
terms of the Bruggeman effective medium approximation.
Inhomogeneous Au films with mass thickness from 1.5 to 10
nm on glass substrates were characterized by spectroscopic
ellipsometry (I. Valyukh).
Active optical elements Diffractive elements based on liquid
crystals are studied with focus on non-uniform alignment conditions that enable us to achieve the needed distribution of the
liquid crystal molecules under a uniform external electric field.
(S. Valyukh). An objective LC micro-lens array for a display
located at the immediate vicinity of the eye has been proposed.
The developed micro-lens array changes optical power from
0 to up to 5000 dioptres and is a promising technique for
augmented reality. (S. Valyukh). Non-absorptive flat thin reflectors, based on cholesteric liquid crystal polymers, with specific
spectral and spatial characteristics have been developed and
patented. Among the areas of applications are optoelectronics
and photovoltaics (S. Valyukh).
Proteins and cells at interfaces In collaboration with Håkan
Engqvist, UU, (SSF Strategic Research Center, MS2E) surfaces
aimed for bone replacements are examined. (T. Berlind).
Cellulose films and chitin films In collaboration with Lars
Wågberg, KTH, optical properties of cellulose films and humidity induced changes are studied with in situ spectroscopic
ellipsometry.
The optical properties of dip-coated chitin thin films are
also studied. Chitin is a semi-crystalline biopolymer found in
the beetle’s cuticle as nanofibrils in a helical lamella structure
which is responsible of the fascinating and complex polarization properties. In situ spectroscopic ellipsometry is used to
study the changes induced in amorphous and semi-crystalline
chitin thin films by humidity and temperature (Muñoz, Mendoza, Järrendahl, de Mayolo, Arwin).
Scientific output 2012 8 publications, and 24 conference contributions including 3 invited talks.

faces deployable at a comparable scale and the formulation of
solutions, which demand neither permanent modifications nor
additional peripherals.
Disposable lab-on-a-chip (LOC) devices can satisfy these
requirements, if the measurement principle can accommodate
the desired analytical performance. In 2012, Filippini’s groups
demonstrated the first angle-resolved surface plasmon resonance (SPR) detection system that is based on a single disposable device, which is configured to use conditioned illumination
and optical detection from cell phones.
The SPR coupler central to this implementation is compatible
with regular (LOC) technology and temporarily adheres to the
phone screen surface during the measurement; it couples and
conditions the illumination from the screen and directs the
SPR image to the phone camera. After the measurement, the
device can be detached and disposed of, thereby leaving the
phone intact.
SPR detection, within diagnostics range, was illustrated with
a commercial assay for β2 microglobulin (β2M), which is an
established marker for cancer, inflammatory disorders, and
kidney disease, which are relevant candidates for complementary monitoring in decentralized conditions.
General information
applied physics
The research within the Division of Applied Physics is multidisciplinary. The members of the division are electrical
engineers, physicists, chemists, biochemists and biologists.
Several projects are in the areas between physics and chemistry, and physics and biology. The projects are often conducted
in collaboration with other divisions within the three scientific
branches of Applied Physics, Material Science and Chemistry.
The research activities also include fundamental multidisciplinary research, mainly within the surface sciences. Many
projects are run in cooperation with external collaborators.
The division is hosting Forum Scientium, a multidisciplinary
doctoral student programme under the direction of Dr Stefan
Klintström. See more under “Graduate education”.
The division also participates in two VINNOVA-graduate
schools: Forum Securitatis, a graduate school in security research and AgoraLink, an agora for Medical and Life Science
Technologies in Linköping.
Research overview, Highlights, and Collaborations
The research within the Division is conducted in collaboration
with many different parts of IFM and with larger programs
described elsewhere. This means that some activities are more
extensively described at other places in the Activity Report.
The research groups within the Division of Applied Physics are
led by:
• Ass prof Mats Eriksson
• Ass prof Daniel Filippini
• Dr Anke Suska
Research group Daniel Filippini
Optical Devices Lab
Daniel Filippini’s group works on optical chemical sensing
methods and devices. One important area of the group’s activity is on physically interfacing chemical sensing techniques
to operate on consumer electronic devices (CEDs). The other
main research focus is microfabrication methods for disposable optics and fluidics.
CEDs sensing ubiquity is restricted by the availability of the
chemical sensing element and accessories rather than the CED
platform itself. Hence, the critical requirements for cell phone
applications are the development of chemical sensing inter-

“Microelectrode arrays for drinking water quality monitoring”
is an ongoing project financed by Formas and running 20112014. In this project new sensors with improved properties for
drinking water monitoring, such as improved detection limits
and faster response times, are developed. Several types of arrays are investigated as well as a new type of printed electronics microband structure (see figure), developed by the groups

Summary:
Research in biomolecular and organic electronics is focused on
the development of polymer electronics, particularly polymer
photovoltaics, and the combination of biological macromolecules with synthetic conjugated polymers for supramolecular
materials assembly. We published 14 papers during 2012.
Biomolecular electronics
The group is furthermore involved in a project within the
VINNOVA program “Challenge-driven innovation”. The
project name is “Online sensor system for resource-efficient
water management (Sensation)”, it has 23 partners, is running
during 2012-2014 and is coordinated by Acreo. The role of the
Eriksson group is to provide “electronic tongues and noses” for
online water monitoring in field tests, in particular for detection of microbial contaminations and petroleum products.
During 2012, the PhD work of Zafar Iqbal was completed
and resulted in a thesis entitled “Optical Sensing with an Ordinary Mobile Phone”. The thesis contains several investigations
of the possibilities and weaknesses of a standard mobile phone
for use as a simplified and ubiquitous spectrophotometric unit.
During 2012, we have initiated an effort to build up a
Linköping research environment on raw water and drinking
water monitoring and to develop new methods that have the
capacity to rapidly capture changes and disturbances in drinking water production and distribution. The proposed research
environment consists of several research groups at Linköping
University and at FOI. A first research application for funding
was submitted at the end of 2012.

Photovoltaics
We have evaluated the anisotropy of the charge transfer state,
which is an intermediate state on the path to photocurrent in
polymer/fullerene devices, through materials and device studies of oriented polymer systems. Semi-transparent solar cells based on modified ITO cathodes combined with transparent polymer anodes have been
developed. Stacking a number of these cells on top leads to a
higher photocurrent than can be obtained by a standard geometry, where a reflective metal act both as cathode and mirror.
With these semitransparent solar cells, we have also recouped
some of the transmitted photons with the help of an external
micropatterned metal reflector, which is superior compared to
a flat metal mirror in improving the total amount of absorbed
photons in the active device.
We investigated the effects of poly(ethylene oxide) (PEO)
modified ZnO nanoparticle as electron acceptors in Hybrid Solar Cells. Compare with reference device using ZnO as electron
acceptor, after PEO modification, all the device parameters are
enhanced. Typically, the PCE was enhanced by 42% increase.
When ZnO used as an interfacial layer between ITO and active
layers in inverted OSCs, the best inverted solar cells were the
ones based on the smoothest ZnO layers, with the largest D/A
interfacial area, and lowest ZnO/active layer interfacial area.
We found that the performance of inverted OSCs can also
be improved with PEO modified ZnO nanoparticles (NPs) as
interfacial layers. PEO modified ZnO surface can effectively
passivate the surface traps of ZnO, suppress the combination
loss of carriers, reduce the series resistance, and improve the
electrical coupling of ZnO/active layer. PCE could be increased
from 4.4% to 5.7%.

to that of a reference microelectrode than to that of a macro electrode, both
in terms of size and time dependence.
We published in Science the first generation of biopolymer
based polymer electrodes, where a electronic polymer is storing
charge in a biopolymer which is modified to be electroactive.
Further developments of polymer electrodes incorporating
electroactive biopolymers has been done. By adding small quinone compounds into the biopolymer composites, considerable
improvement of charge densities is obtained. These polymer
electrodes are of relevance for energy storage in supercapacitors and possibly in secondary batteries based on aqueous
electrolytes.
Decoration of DNA chains with metallic conjugated polyelectrolytes has been accomplished. Stretched and aligned
decorated DNA chains acts as the conducting channel in a electrochemical transistor geometry, with sparsely printed wires
connecting two electrode pads.
We have prepared self-assembled protein structures incorporating iron oxide nanoparticles. Moreover, these hybrid materials have been used as test systems in electron tomography
measurements.

Wearable Contact Lens Biosensors with Nanoengineered
Architecture Interface. LIST (2012-2013), 350k SEK
This interdisciplinary project bridges research activity in the
Biosensors and Bioelectronics Centre on wearable biosensors
for non-invasive ocular diagnostics and work at the Integrative
Regenerative Medicine (IGEN) Centre on cornea regenerative
medicine for infection-associated corneal transplant rejection.
Ocular fluid is an extracellular fluid excreted from the tear
gland. With recent advances in proteomic technology, several
important biomarkers from ocular fluid have been identified
having significant clinical diagnostic value for various diseases.
The contact lens is disposable, relatively cheap and serves as
a platform to obtain direct intimate contact with ocular fluid,
which is an attractive and a promising platform for non-invasive diagnostics. With support from LIST, Masters student Jenny Orban is being supervised by Wing Cheung Mak to develop
surface engineering techniques integrating a biorecognition
layer onto contact lens surfaces. This exploratory project will
serve as a foundation for the future development of wearable
biosensors. Our long-term goal is to develop simple, inexpensive and non-invasive contact lens-based wearable biosensors
for rapid screening of different potential health risk factors in
ocular fluid.
are supervising a visiting student from Lomonosov Moscow
State University (Alina Sekretaryova) funded by “The Visby
Program – Swedish Institute’s Baltic Sea Region Exchange
Program”. Alina is working on two main areas: i) the development of an electrochemical mediated enzyme sensor for the
detection of cholesterol and the ii) characterisation of novel
mediators for oxidase-based biosensors.
Cell microencapsulation and monitoring: towards cell therapy
Delivery of stem cells to target tissues for tissue regeneration is extremely challenging. Stem cell microencapsulation
provides a new strategy, which may improve the effectiveness
of cell delivery to the target tissue by creating a semi-permeable
container separating the encapsulated cells and the environment. In parallel, monitoring of the encapsulated cells inside
the microcapsule environment is important to optimise the
microcapsule construct design and therapeutic efficacy. We
have initiated collaboration with IGEN on integrated stem-cell
encapsulation and monitoring for tracking the well-being of the
encapsulated stem cells for cell therapy. Master student, Inés
Moreno from Cranfield University (UK) is being supervised by
Wing Cheung Mak, to develop encapsulation techniques based
on hydrogel materials and to perform cell monitoring within
microcapsules. The focus is on controlling and monitoring
proliferation of stem cells within microcapsules and testing encapsulated Human Umbilical Vein Endothelial Cells (HUVEC)
for use as a cardiac patch for heart muscle regeneration.
Nanobioreactors, stimuli-responsive and intelligent carrier/scaffolds
for bioelectronics, drug delivery, imaging and tissue engineering
Swedish Research (VR) Council (2012-2016) 4m SEK
In addition to our nanobioreactor work decribed in the previous report, temperature-, pH-, magneto- and photo-switchable
nanomaterials are being integrated into high-order dignostic
devices with switchable bioelectronics and modulated biochemical processing. Reversible immunosensors have been designed
for the cardiac injury marker, troponin, using both antibodies and molecularly-imprinted polymers. These biomimetic
biosensors serve as a model for the design of other affinity
sensors for cardiac, genetic and infectious diseases. We are also
exploring the use of these smart materials for targeted drug delivery using smart nanocarriers in conjunction with magnetic
resonance imagin (MRI) and exploiting their hyperthermic
properties for tumor treatment. Stimuli-responsive polymeric
unimolecular micelles, formed from pH- and temperatureresponsive block copolymers, provide a unique core-shell
architecture wherein the hydrophobic core serves as a natural
carrier environment for hydrophobic drugs and the hydrophilic shell allows particle stabilisation in aqueous solution. A
metallic core can also be introduced into the particle, endowing
the particle with optical, magnetic or hyperthermic properties.
These novel micelles will contain three key components: (i) a
chemotherapeutic agent doxorubicin that will be released from
polymeric micelles through a pH-dependent mechanism; (ii)
a biological ligand, i.e., specific aptamer that can target tumor
cells and subsequently induce receptor-mediated endocytosis
for cell uptake; and (iii) a metallic core for ultrasensitive MRI
or hyperthermic properties.
Enzyme sensors

applied physics
Gifford and Tony Turner realised a first demonstrator of an
all-printed biosensing system, where not only is the amperometric sensor printed, but all the associated elements such as
battery, display and circuitry are printed on a single sheet of
PET and then laminated in an appropriate casing. The picture
below shows the reality to date, a prototype functioning system.
Glucose concentration can be measured in a few seconds and
observed via the printed display using this device, powered by
a printed battery. Rudimentary silicon circuitry can be seen to
the right of the picture, but this could be readily integrated into
a tiny, inexpensive silicon chip. This device is being used as
a concept demonstrator to develop a range on new products,
principally for medical diagnostics.
Biosensors for environmental analysis:
Salmonella typhimurium
S. typhimurium has been identified by the WHO as the most
common source of food-borne illness worldwide. Traditionally,
microorganisms are detected and quantified by culture and
colony count; this is time consuming and requires well-established laboratory facilities. In an effort to reduce analysis time
and costs, and to move to on-site analysis, Valerio Beni is working, in collaboration with the Nanobioengineering group at
the Institute for Bioengineering of Catalonia (IBEC), Spain, on
the development of electrochemical aptamer-based biosensors. As part of this collaboration, Jose Luise Sebastian Avila (PhD
student) visited Linköping University for four months. Funded
by “The Ministerio de la Ciencia de Espana”, he designed and
tested a series of different assay formats using aptamers as
recognition/capture elements with enzymatic labels for electrochemical detection.

Kanamycin A
Contamination of aqueous environments with pharmaceutical
residues has an important impact on the environment and on
human/animal health; the presence of antibiotics can promote,
for example, multi-drug resistance in pathogens. With the aim
of improving water quality, we are developing, in collaboration with the working group “Biological on-site measuring
Methods” at the Helmholtz Centre for Environmental Research
(UFZ) in Leipzig, Germany, an electrochemical aptasensor for
the rapid screening of Kanamycin A in water,. This collaboration was generated as part of the COST action TD1003 on
Bioinspired Nanotechnologies. The electrochemical biosensor
took advantage of the ability of the aptamer, selected at UFZ,
to undergo a competition event between the target and an onsurface immobilised probe. Electrochemical monitoring of the
recognition event is performed by the use of electrochemical
impedance spectroscopy or by the voltammetric monitoring
of the presence of a redox centre (Methylene blue) synthetically introduced at one end of the aptamer. The project was
supervised by Valerio Beni and carried out by Aristide Ganci, a
visiting Master student from Cranfield University (UK) and is
being continued by Presty Mathew, a LiU Master student.

Polymer actuators:
We are currently working on new materials development,
micromechanical stimulation, microrobotics and novel actuator
designs. We have developed novel polypyrrole-based actuator
materials to investigate the role of crosslinking in the actuation
mechanism. Daniel Melling from Cranfield University, who
Edwin Jager externally supervised during his PhD, continues
to visit the Biosensor and Bioelectronics Centre as a part of this
project. We have a collaboration with the Italian Institute of
Technology, Center for Micro-BioRobotics, in Pontedera, Italy,
developing all polymer soft actuators and new bioinspired propulsion schemes. As a part of the ongoing collaboration with
the Intelligent Polymer Research Institute (IPRI), at University
of Wollongong, Australia, Edwin Jager visited IPRI during the
summer of 2012 to continue work on microfabricating new
soft actuators that work in air. In parallel two MSc students,
Nnamdi Felix Nworah and Nirul Masurkar, worked on this
project at LiU. We successfully demonstrated new fabrication
and interfacing methods and a paper has been submitted. As
a part of the COST MP1003, Dr. Janno Torop worked on novel
PPy hybrid materials. This work resulted in a Carl Trygger Stiftelsen grant and he will join the group as post-doc in 2013. A
second STSM was performed by José Martinez, a visiting PhD
student from the University of Cartagena, Spain. He stayed in
the group for 3 months utilising our specialised laser scanner
micrometer for measuring the volume change of PPy as a part
of the modeling work on PPy actuation.

Bioelectronics:
PhD student Mohsen Golabi is investigating a novel concept
based on surface interactions to detect and identify different strains of bacteria. We recently expanded this project to
include quorum sensing molecules, in collaboration with Dr
Elena Vikström and Prof Karl-Eric Magnusson at the division
of Medical Microbiology at campus US. A project developing
electroactive fibre scaffolds for increased stem cell differentiation, in collaboration with Dr Mehrdad Rafat at Campus US,
has gained important momentum from an IGEN grant. Amy
Gelmi joined the team in October this year as a post doc to
develop these novel fibre-based scaffolds. We have recently fab28
Highly stable surface chemistry for genosensors
As part of a long-standing collaboration with the Universitat
Rovira I Virgili, PhD student Mabel Torrens del Valle came to
visit the Centre to investigate the use of micro-contact printing and aryl diazonium salt assembly for the preparation of a
highly stable sensing surface for genetic analysis of pathogens.
A novel approach based on the catalytic activation of the aryl
diazonium salts was developed allowing spontaneous stable
grafting of aryl diazonium salt on different substrates such as
carbon, Au, Pt and PDOT. The surfaces had high chemical stability and were suitable, following the immobilisation of DNA
probes, for electrochemical genosensing. Characterisation of
the prepared surfaces is currently on going in collaboration
with Dr Johan Hurtig (Molecular Physics). The use of the approach for the functionalisation of siliconcarbide and graphene
is also under investigation in collaboration with Graphensic.
Automatic synthesis of plastic antibodies
A recent paper in Advanced Functional Materials (Poma et al.)
describes an automatic solid-phase photo-reactor developed
in collaboration with Cranfield University (UK). At the core of
the reactor is an immobilised template, which can be a small
molecule, peptide or whole protein. This ensures that surfaceconfined imprints are formed only on one face of polymer
nanoparticles and that the template can be reused for the synthesis of subsequent batches of imprinted polymer. The reactor
integrates template-directed synthesis with affinity separation,
a combination which ensures the production of monoclonaltype molecularly-imprinted nanoparticles. Batches of 100 mg of
particles can be produced in each six-hour cycle with templates
including melamine ((KD= 7x10-10 M), vancomycin (KD= 1.9x10-10M), a model peptide (5.5x10-12 M) and various proteins
(KD= 10-11-10-9 M for trypsin, pepsin, amylase, peroxidase).
Affinity measurements were obtained using a SPR sensor
(Biacore 3000).
TEACHING
The Biosensors and Bioelectronics division has greatly
strengthened its role in education during 2012 by designing
and giving a series of courses, comprising tutorials, lectures
and practical classes. The division runs key courses in the area
of biosensors including: Introduction to biosensor technology
(TFYA62 – Valerio Beni), dedicated to 2nd year students of
the Biomedical Engineering bachelor degree and the advanced
Masters course “Biosensors Technology” (TFTB34 – Fredrik
Winquist). Edwin Jager presented several lectures for Microsystem Technology and Nanobiology (TFTB33), Biomedical
Materials (TFTB40) and the PhD course Organic Electronics
and Tony Turner delivered a number of guest lectures to LiU
students. The group has also been engaged at various levels
in the design of new courses, mainly at PhD level, that will
run from 2013. These include: “Colloids and Interfaces” (Wing
Cheung Mak) and Integrated Nanomaterials and Medical
Devices’ (Ashutosh Tiwari). Moreover some of the group have
been also involved in design of the course “Experimental Electrochemistry / Electroanalyical Methods”, an effort led by the
Biomolecular and Organic Electronics group. Finally the group
has been actively involved in the design of CDIO projects
(TFTB36 and TBMT41).
applied physics
This generic approach to the automated synthesis of polymer nanoparticles provides material of ”monoclonal” quality
produced in a consistent and reproducible manner, suitable
for use as a direct replacement for antibodies in a variety of applications. It offers speed of synthesis and multiple batches of
polymer nanoparticles can be produced in 24 h under continuous computer control. Template re-use and in-built affinity
separation also ensure consistent, economic and high-quality
production.
Another relatively new imprinting approach that is particularly useful for electrochemical sensors uses electroploymerisation of a thin film of the recognition element directly on the
sensor surface. The ability to precisely control the thickness of
the layer and the fact that it is generated in situ, makes this an
attractive alternative. In so far unpublished work, we showed
that a troponin sensor could be prepared by electropolymerisation of o-phenylenediamine on a gold electrode in the presence
of troponin as a template. Measurements were performed in
the presence of 5 mmol l−1 K3 Fe(CN)6 and the current generated was inversely proportional to the analyte concentration,
since the measurement depends on occlusion of the electrode
surface by the template. The resulting molecularly-imprinted
troponin biosensor could be used to detect cardiac injury, offering benefits in terms of cost effectiveness, storage stability,
sensitivity and selectivity.

Summary
The research and education at the division of biotechnology
focus on industrial applications of biotechnology. In essence,
industrial biotechnology is the integration of engineering and
biology for production purposes. The scientific breakthroughs
of the seventies and eighties in molecular genetics, which resulted in the industrial production of recombinant proteins in
microbial and animal cell cultures, are now furthered by new
products such as stem cells, therapeutic antibodies and gene
therapy vectors. A number of bioengineering tools are currently exploited based on genetic, protein, metabolic, physiological
and organ engineering in order to improve production capacity of proteins, metabolites, and cells. It is a prime task for the
current biotechnology research to integrate and develop these
tools in order to achieve and optimize new and better industrial
applications. The biotechnology division at IFM is contributing to this by inventing and developing novel analytical means
that can provide better insights into the biology of industrial
production systems. The cross-disciplinary environment of
Linköping University furnishes unique opportunities for this.
The combination of sensor technology, mathematical computation methods and production design, supports the use of new
approaches that enhance the understanding and allow further
optimization of the bio-industrial production systems. The
integration of these topics in the curricula of the Engineering
Biology program forms an important link between education
and research at the division. Our PhD-study program in biotechnology is directly connected to the research of the division
and is a part of the research that is highlighted below.
The division has together with 40 partners received a five year
IMI project – STEMBANCC - on induced pluripotent stem cells.
The aim of the project is to generate and characterise 1 500
high quality human induced pluripotent stem (iPS) cell lines
that can be used by researchers to study a range of diseases,
including diabetes and dementia, and test for drug efficacy and
safety. The cell lines will help to improve and speed up the drug
development process, and ensure that patients benefit from
more effective and safer drugs. Mandenius is the leader of the
in vitro assay development in the project.

New project on Lab on a Chip for toxicity testing
Together with the group of Dr Nate Robinson at IFM we study
new designs of Lab on a Chip for toxicity testing. The project is
supported by the Swedish Research Council program for reducing animal testing.
Soft sensors for bioprocess monitoring and control
Soft sensors are robust on-line sensors supported by mathematical models derived from the systems under study. In
particular, they are useful for bioprocess monitoring due to
the complexity of the biological mechanisms of the producing
cells. We have used soft sensors to monitor physiological signals from typical industrial cultures by combining sensors for
biomass, effluent gases and key metabolites with basic mass
balances and kinetic (Gustavsson and Mandenius, Bioprocess
Biosystems Engineering, 2012). Also, a conference talk was
given by Robert Gustavsson at the 15th European Congress of
Biotechnology in Istanbul.

Virtual Bioreactor Training
In collaboration with the University of Applied Science in
Bremen, and with support from PUG at the technical faculty,
we have continued to develop new virtual tools. One of these is
a virtual bioreactor that mimics the operator environment in a
biotech production plant. It allows the engineering students to
apply monitoring and control methods in a hands-on fashion.
The goal is to strengthen the link between engineering theory
and practice with the aim to make the students better prepared
for professional life.

Education
The division has during 2012 delivered three advanced level
courses in the Engineering Biology/Chemical Biology programs (Industrial Biotechnology, 6 hp; Bioprocess design, 6
hp; and Bioprocess manufacturing, 6 hp) and examined several
diploma work theses in biotechnology.
2. SUMMARY
The division of Molecular Physics conducts fundamental and
applied research in three closely related fields of biologically
inspired surface and nanoscience: Biosensing and biochip technology; molecular/polymer thin film physics and spectroscopy;
and nanoscale physics/chemistry.
The fundamental part of the biosensing and biochip research
is devoted to the design and synthesis of surface active compounds and new biorecognition molecules. Polypeptide as well
as carbohydrate recognition molecules are synthesized and
evaluated using the above mentioned transducer platforms. We
are also working with de novo synthesized helix-loop-helix polypeptides and minimized sequence peptides for microarrays.
A significant portion of the research utilizes solution selfassembly techniques to produce novel surface architectures
and materials. A new type of oligomeric monolayers forms the
base for our investigations, and through a fruitful combination
of surface vibrational spectroscopy and quantum chemical ab
initio calculations we have improved the understanding of the
mechanisms that influence the phase behaviour and orientation in such layers.
Several projects utilize nanoparticle plasmonics for sensing
applications. We are particularly interested in using gold and
silver particles for studies of metal-enhanced optical phenomena such as metal enhanced extinction (MEE) or metal-enhanced fluorescence (MEF), or using localized surface plasmon
resonance (SPR) for improved imaging. Some of these projects are carried out with the School of Materials Science and
Engineering, Nanyang Technological University, Singapore.
The plasmonic research also relates also to our activities on
helix-loop-helix polypeptides for controlled aggregation of gold
nanoparticles (NPs) into functional entities.
Our long-standing research on antifouling surfaces has
somewhat shifted focus from biomedical to marine biofouling applications over the last few years, and is now conducted
primarily through our involvement in the Marie Curie Initial
Training Network SEACOAT. The network involves research
in three complementary, interdisciplinary themes: surface
engineering, surface analytics and bioadhesion. An important
part of our research in marine biofouling is the development
of real-time methods for monitoring of surface interactions of

marine organisms. For this purpose, a recently acquired laserTIRF microscope with an integrated imaging SPR facility will
be of great importance.
The Molecular Physics division is deeply involved in the initiative on Regenerative Medicine headed by Prof May Griffith,
and which is now in its third year. The laboratories for polymer
science and peptide chemistry at the division serve other partners in the project with new materials and molecules, and also
provide advanced tools for the characterization of the developed
materials and implants, thus contributing to a concerted effort
to make translational technologies (bench-top to bed-side) a
reality.
Staff at the division are also involved in undergraduate teaching, giving advanced courses on surface and supramolecular
chemistry, spectroscopy and biomedical materials.
Daniel Aili was recruited as a LiU-Forskarassistent in 2011
and has during 2012 received extensive funding from both the
Swedish Foundation for Strategic Research (Ingvar Carlsson
Award) and the Swedish Research Council (VR) to pursue
research on responsive hybrid materials, leading to a considerable expansion of the division over the last year. Aili was also
awarded the AkzoNobel Nordic Prize in Surface and Colloid
chemistry.
3. HIGHLIGHTS
Chelation assisted photoimmobilization – a novel route to covalent, oriented
protein immobilization
applied physics
Karin Enander, Bo Liedberg, PhD student: Emma Ericsson. A novel
two-step method for homogenous orientation and covalent
attachment of His-tagged proteins to sensor surfaces has been
developed, where a chelating agent (nitrilotriacetic acid, NTA)
captures the protein in an oriented fashion followed by covalent
tethering by the reaction with a photolabile group (benzophenone, BP). The strategy was demonstrated on gold sensor
surfaces with mixed self-assembled monolayers of NTA- and
BP-presenting alkanethiolates. Although homogeneous ligand
orientation is less crucial for analyte accessibility in the case
of multivalent ligands, this strategy may prove very useful for
monovalent ligand-analyte interactions, offering a well-defined
mode of immobilization suitable for microchip photopatterning applications.
Detailed molecular characterization of thrombin-par4 interactions
Karin Enander, PhD student: Robert Selegård. In a recently
formed collaboration with Prof Tomas Lindahl and Dr Sofia
Ramström (Laboratory for Clinical Chemistry, Department of
Clinical and Experimental Medicine, LiU) we use surface plasmon resonance-based analysis to characterize low-affinity interactions between thrombin and polypeptides corresponding to
the extracellular loops of the human PAR4 receptor expressed
on platelets. Our ambition is to map sites in both thrombin and
the receptor that contribute to the interaction, which is crucial
for platelet activation during blood coagulation.
Interfacial charge and swelling of layered polyelectrolyte hydrogel gradients
Thomas Ederth. PhD student: Feng-I Tai. Hydrogel patterns and
gradients are of immediate interest for biochip and protein
array technology. In sandwiched thickness gradients of anionic
and cationic polymers, charge neutral regions are very resistant
to non-specific protein adsorption. We have prepared twocomponent hydrogels (Figure 1) with a charged uniform bottom layer, an oppositely charged thickness gradient is grafted.
The location of the charge neutral region along the gradient
depends on the pH, and direct force measurements using a
32
charged colloidal probe is used to study the complex swelling
behaviour of the hydrogels and monitor the shift of this minimum as the pH is changed.
Figure 1. Top: schematic of a two-component hydrogel gradient. Below: AFM
force curves obtained using a negatively charged probe on a P(AEMA-CEA)
gradient, showing re-location of the charge-neutral region.
Lipid membrane architectures
Johan Hurtig. Funds from the Magn. Bergwall and Carl Trygger Foundations have permitted acquisition of a fluorescence
microscope with an ultrasensitive camera detector. This is used
in projects related to control of directional growth of intercellular nanotubes through micropatterned substrates as well as
nanosurgical extraction of cell material. The investigation of
intercellular nanotubes is based on an interdisciplinary approach between microfluidic sample handling, nanopatterned
substrates and sensitive detection technologies to probe a new
eukaryotic cell-cell communication strategy.
Mechanisms for lysosomotropic destabilization of membranes
Thomas Ederth, PhD student: Timmy Fyrner. Lysosomes are
vesicular organelles found in virtually all eukaryotic cells and
are involved in macromolecule turnover and thus contain
numerous hydrolytic enzymes, digesting unwanted material in the cell. Lysosomes are also involved in apoptosis; the
lysosomal membrane is permeabilized in response to cell
death stimuli, although the mechanisms behind this are poorly
understood. In collaboration with Karin Öllinger (Faculty of
Health Sciences, LiU), and Atul Parikh (UC Davis) we investigate mechanisms for lysosomal membrane destabilization by
natural and synthetic lysosomotropic detergents.
Local refractive index sensing based on metal nanostructures
Bo Liedberg, Daniel Aili, PhD students: Erik Martinsson. We
develop optical biosensors based on detection of small local
refractive index changes in the vicinity of metal nanostructures. In cooperation with a group at the School of Materials
Science and Engineering, Nanyang Technological University,
Singapore we have explored the bulk and surface refractive
index sensitivity of core-shell Ag@Au nanoprisms, finding that
these are much more sensitive to local refractive index changes
than both conventional surface plasmon resonance as well as
spherical gold nanoparticles (Figure 2). We aim to integrate
these nanostructures as sensing elements in optical biosensors
in order to monitor biomolecular reactions occurring in the
proximity of the nanostructures.
Regenerative Medicine
Figure 2: A comparison of surface refractive index sensitivity between coreshell Ag@Au nanoprisms, conventional SPR and spherical Au nanoparticles.
Peptide-polymer hybrid materials
Daniel Aili, Post-doc: Staffan Dånmark, PhD student: Christopher
Aronsson. We develop peptide- and polymer hybrids for selfassembly of hydrogels with well-defined and tunable properties
for biomedical applications. The peptides are designed to fold
into coiled-coil heterodimers with high structural integrity,
low KD for dimerization, and controllable/tunable assemblyand oligomerization-properties.. The peptides are modified to
promote polypeptide fiber-formation but can also be covalently
attached to polymer scaffolds based on hyaluronic acid and poly
ethylene glycol. Polymer scaffolds are currently being modified
for conjugation with the peptides.
Linköping Integrative Regenerative Medicine Centre (IGEN),
funded by LiU and the County of Östergötland, enables multidisciplinary teams to work together to develop bold innovative
treatment methods that will restore function to damaged or
diseased organs and tissue. The activities within regenerative
medicine at IFM include design and preparation of new biomaterials and bioactive molecules, and provision of advanced
tools for the characterization of the developed materials and
implants.
Collagen-based scaffolds and hydrogels
May Griffith, PhD student: Abeni Wickham. A large focus is
on development of different strategies for collagen scaffold
formation. We are now able to make the collagen and cellulose
as a hydrogel (90% water), collagen electrospun fibers, and
highly dense collagen meshes (5% water). The latter material
is very similar to the Apligraf® used for wound treatment and
has now become the material emphasis for the collaboration

Self-assembly of anisotropic nanostructures
Daniel Aili, Karin Enander, PhD student: Camilla Sandén. The aim
of this project is to develop well-defined and biocompatible nanoscale components for modular self-assembly of anisotropic
hybrid materials using reconstituted high-density lipoprotein
(rHDL) as a supramolecular template. The rHDL is functionalized to specifically associate with gold nanoparticles and to
form well-defined and discrete nanostructures with interesting
and useful optical properties. The synthesis of rHDL has been
optimized and several strategies for functionalization and assembly of the nanostructures have been evaluated.

Our objective is to develop designer scaffolds using polymeric
multiarm templates conjugated with collagen-mimetic peptides
(CMPs) which can self-assemble into collagen-like triple helical
networks. Collagen forms the basic scaffolding of virtually
every organ, but is susceptible to enzymatic degradation. This
can be circumvented by CMPs with the desired properties of
collagen but whose stability can be controlled. A CMP conjugated with 8-arm PEG maleimide template forms a selfsupporting transparent hydrogel suitable for corneal implant.
The hydrogel supported the growth and proliferation of human
corneal epithelial cells and has shown significantly higher enzymatic stability compared with EDC/NHS cross-linked human
recombinant collagen hydrogels, currently in phase-2 human
clinical trials for the corneal regeneration.

General
The division of Molecular Surface Physics and Nano Science is
a division at Applied Physics IFM, active in the field of Nanomaterial and Molecular thin film physics and spectroscopy. Our
main focus is on surface modification for sensing/biorecognition and nanoprobes for biomedical imaging. Biospecific
binding phenomena at solid surfaces are investigated. Design
and characterization of new and improved nanoprobes for
imaging are performed. Equipment used are X-ray Photoelectron Spectroscopy (XPS), Photoemission electron Microscopy
(PEEM) Near Edge X-ray Absorption Fine Structure (NEXAFS) Spectroscopy, Infrared Absorption Spectroscopy (IRAS),
Dynamic Light Scattering (DLS), Transmission Electron
Microscopy (TEM), computed tomography (CT) and Magnetic
Resonance Imaging (MRI). Super small particles i.e. particles
with very small volume, with unique physical and chemical
properties, have a high potential in biomedical imaging and
future biosensing applications. We are designing biocompatible nanoparticles based on rare earth metal oxides. These are
very promising as positive contrast agent (Patents) in MRI and
CT. Powerful equipment available at IFM, in house experience
of life science technology and molecular physics as well as
close collaboration with CMIV (Center for Medical Image Science and Visualization) facilitate progress in the field of novel
nanomaterial design for bio medical imaging.

Nanoparticles for biomedical imaging In this project we are designing and characterizing rare earth nanoparticles to
optimize the contrast in magnetic resonance imaging (MRI).
This project includes material design and synthesis, characterization, surface modification, biofunctionalization and signal
optimization followed by tagging for targeting purposes.
The synthesis of the material is done in close collaboration
with Inorganic Chemistry and bioorganic chemistry, IFM.
The MR signal optimization is done in cooperation with the
Center for Medical Image Science and Visualization (CMIV) at
the medical faculty and University Hospital. We have shown
that the relaxation properties of this contrast agent have an
enhancing capability with respect of MRI signal, compared to
the commercially available ion based Gd-DTPA contrast agent.
With this new contrast agent the aim is to obtain higher resolu-
tion, tissue specific images and cell- and molecular imaging.
Knowledge obtained with in the project will contribute to
the understanding of drug delivery targeting. Our goal is to
improve the contrast to enable high resolution imaging for e.g.
early diagnosis of neurodegenerative diseases and cancer. This
is a true interdisciplinary project, combining Physics, Chemistry, Biology and Medicine.

to their capability for signal enhancement. A new interdisciplinary project involving Applied Physics, Organic chemistry,
Pharmacology, CMIV and Clinical and Experimental Medicine to develop nanoprobes for biomedial imaging and tumor
targeting. Our vision is to design calcium-receptor targeted
nanoprobes with luminescence and magnetic properties, with
the capability to specifically image.

Supramolecular approach to nanoscale metal-containing gels,
fibers, belts, and rods. The ligand-structure effect and mechanism of 1D growth of nanofibers have been studied. Cu-L1 acts
as “super-gelators” representing one of the rare examples of
metallogelators with very good selectivity to Cu(II) over other
metal ions. These dynamic gels and nanofibers exhibit solvent
mediated shape transformation by stimulation of ultrasound.
The shape control and the study of the structure effect at the
molecular level in this work will certainly expand the synthesis

new functional materials.

GRAPHENE SENSORS
Mono- and bilayer graphene, epitaxially grown on SiC in the
group of Prof Rositza Yakimova, Material Science Div was characterized for gas sensing and shows ultra-low detection limit,
less than 10 ppb of NO2. It was shown that upon exposure to
electron acceptors (oxygen, water vapour, NO2) or donators
(NH3), the relative Fermi level in single layer graphene suffers
a greater change than that in bilayer graphene, (R. Pearce, J.
Eriksson, T. Iakimov, L. Hultman, A. Lloyd Spetz and R. Yakimova, ACS nano, accepted). The graphene sensor research is
supported within FunMat and AFM - Strategic Faculty Grant in
Advanced Functional Materials. A patent was filed regarding a
smart sensor device based on graphene/ SiC. Also MAX based mono- or few layer materials like MXene (TiC) are investigated
according to gas sensing properties.

SUMMARY
The division consists of two research groups: Organic Physics
(Fahlman, Bao, Braun, Liu, Sehati, Shi, Sun) and Transport and
Separations (Robinson, Bengtsson, Erlandsson, Nilsson). The
Organic Physics research consists of fundamental study and
model development of weakly-interacting organic-organic and
organic-metal interfaces; interface engineering in organic electronics i.e. development of techniques for improving charge injection, exciton dissociation and stability of interfaces in organic
electronic devices; transparent conducting electrodes (graphene,
inorganic oxides) and their interaction with organic electronic
materials; intrinsically conducting polymers such as PEDOT
and PAni: the effect of synthesis and choice of (poly)anion on
conductivity, bio-compatability and general surface properties.
The Organic Physics group also does research focused on the
study and design of hybrid organic spintronic interfaces (spinterfaces) with the aim to understand and improve devices such as
hybrid spin-valves; and the development and study of thin film
organic-based semi-conducting magnets such as V(TCNE)x, x~2,
with the aim to understand and tune materials properties to enable efficient organic spintronic device design and fabrication.
The Transport and Separations group focuses on ionic and
electronic transport in fluids and solid-state materials. One
particular goal of the research is to create and understand new
devices in areas such as micro- and nano-fluidics and solidstate lighting. The group develops pumps for microfluidic
labs-on-chips. In addition to this work, the group studies the
interface between large molecules and conducting surfaces for
applications in separation processes. In addition to the work
on microfluidics, research and development of light-emitting
electrochemical cells are carried out in collaboration with Umeå
University.
Collaborations with specific funding during 2012 included
the EU-FP7 project on Modelling of electronic processes at
interfaces in organic-based electronic devices (MINOTOR, Fahlman PI of LiU), the EU-FP7 project All-carbon platforms for
highly efficient molecular wire-coupled dye-sensitized solar cells
(MOLESOL, Fahlman PI of LiU), the EU-FP7 project Next Generation Hybrid Interfaces for Spintronic Applications (HINTS,
Fahlman PI of LiU) and the EU-FP7 project SUstainable Novel
FLexible Organic Watts Efficiently Reliable (SUNFLOWER, Fahlman PI of LiU).

The division received additional funding from three contracts
issued by the Swedish Research Council (VR) and a contract
from the Swedish Energy Agency.
The division’s involvement in the undergraduate teaching
activities of the university during 2011 consisted of the course
Fysik B (Erlandsson).

By combining XPS, UPS and NEXAFS, we studied the interface
interaction and energy level alignment between dye molecules
(EPFL, IMEC in MOLESOL) and TiO2, shedding light on the
importance of surface defects states in the TiO2 nanocrystals.
By combining XPS, UPS and NEXAFS, we carried out engineering and characterization of graphene and NCD surfaces,
with an emphasis on achieving work function tailoring. (MPIP,
IMEC in MOLESOL).
By combining XPS, UPS and NEXAFS, we studied the chemical interactions, energy level alignment and degradation effects
of materials and interfaces constituting tandem solar cells (GenesInk, BASF, Chalmers, AGFA-Gaevert in SUNFLOWER).
Continued development of the Integer Charge Transfer Model
focused on molecular order effects and energy gradients over
multilayer sysytems was carried out in collaboration with Geert
Brocks and Michel de Jong of the University of Twente (MINOTOR).
Ultraviolet photoelectron spectroscopy, optical absorption,
photoluminescence, and charge carrier mobility versus temperature data was used to determine the contributions from the
polaron binding energy and energetic disorder on the hole-transporting properties of poly(3-hexylthiophene).
By combining XPS and UPS with device performance, mechanisms for engineering charge-injecting interfaces were clarified
By combining XPS, UPS, NEXAFS and XMCD, spin-injecting
hybrid organic interfaces were designed and studied (HINTS
and Fudan collaboration).
The group gave two invited talks and one invited tutorial:

Crete, Greece, July.
Transport and separations group
The Transport and Separations Group has initiated several projects in the area of microfluidic devices. Our LIST project in collaboration with the Imaging and Ubiquitous Chemical Sensing Lab at IFM and the Cell Biology group
at IKE has resulted in microfluidic devices for use in measuring
fucose in urine. We have begun making and testing microbioreactors with
our partners in the Biotechnology group at IFM. These devices
are intended to help reduce the need for animal testing during
chemical toxicity and pharmaceutical evaluations. We have also initiated a project with the Clinical Chemistry
Group at IKE to design microfluidic systems for studying and
analyzing the activation of platelets in blood by shear stress.
-One of the most exciting areas of development is the use of 3D
printing (fabbing) to produce microfluidic devices. We use a 3D
printer capable of extruding soft materials like polymers, allowing us to take advantage of our previously-developed technologies such as the polymer electroosmotic pump and making our
research rather unique in the world.

Within IFM Biology, the research is organised in research
groups, which are ad hoc associations of people working on a
common scientific theme. The groups are dynamic, and can
change their composition as deemed suitable by the involved
people. In the following pages, the research groups active
during this year present their activities.
The PhD-education is carried out within four different
subjects: Ecology, Zoology, Ethology and Molecular Genetics.
Within Ecology, emphasis is on community and population
ecology, including conservation biology, vegetation and wetland
ecology. Here, methodology and temporal trends have been studied in areas such as phenotypic plasticity and seed dormancy.
In Molecular genetics, research training is focusing on plant
molecular biology. In Zoology, research is mainly focused on
developmental aspects of cardiovascular control systems and
comparative olfaction research, and in Ethology, focus is on
domestication effects on behaviour in chickens. The staff is
also heavily involved in undergraduate teaching in all subjects
covering the biological education programs.

of research
The AVIAN Group includes research on behaviour (Per Jensen)
and personality (Hanne Løvlie), physiology (Jordi Altimiras)
and genetics (Dominic Wright).
Although not restricted to it, most of the group’s research
focuses on the ancestral Red Junglefowl and modern chicken
breeds selected for farming purposes such as egg productivity
or meat yield with the goals of understanding the genetic basis
of animal domestication and its functional mechanisms.
As part of the Centre of Excellence in Animal Welfare
Science our research is also dedicated to the improvement of
animal welfare. In 2012, for example, we have shown that early
stress produces life-long and transgenerational modifications
in behaviour, stress reactions and gene expression in chickens
(Goerlich et al, 2012 in Hormones and Behavior).
A Red Junglefowl hatching in the foreground and a White Leghorn hatching

The ethology lab has recently published part of the results from
the fear selection study showing that Red Junglefowl selected for low fear of humans displays correlated responses in a
number of other behaviour traits. The role of two genes, TSHR
and ADRA2C in chicken domestication is also under study,
since they have recently been found to carry a clear signature of
selection. Anders Wirén successfully defended his PhD thesis
entitled “Correlated selection responses in animal domestication: the behavioural effects of a growth QTL in chickens”.
The genetics lab has made important progress in their attempt to dissect complex behavioural and physiological traits
using Quantitative Trait Locus experimental approaches. Their
paper in PLoS Genetics (Johnsson et al. 2012, A sexual ornament in chickens is affected by pleiotropic alleles at HAO1 and
BMP2, selected during domestication) received a lot of media
attention and demonstrated how two genes that were responsible for increasing comb mass also increased egg production
and bone allocation. This revealed at a genetic level how a
sexual ornament (the comb) can have pleiotropic effects on
other traits.

group has shown distinct differences in the mechanisms of
cardiovascular regulation in different chickens breeds (Crossley
and Altimiras, 2012 in Poultry Science). The group is also collaborating with Alvaro Garitano from Universidad Mayor de San
Andrés in La Paz, Bolivia in the study of cardiac function in the
Ornate Tinamou, a primitive bird that thrives in the Andean
Altiplano at 4000 meters above sea level. To support the increasing need for studies in cellular models a new cell culture
facility was installed and studies on the growth of cardiac cells
in response to different hormones and environmental factors
are being carried out.

Research during 2012 focused on insect, trees, species-rich
grasslands and deciduous forests.
Many species of insects and fungi, including many rare ones, depend on
forest fires. Preserving such species constitute a major challenge, and is
likely to benefit from a landscape perspective
COOPERATION
Our projects involve cooperation with a number of universities
and research institutes, e.g. University of Lund, Sweden; SLU
(Uppsala, Alnarp, Umeå), Sweden; Mid Sweden University,
Sweden; Oklahoma State University, USA; Middle Tennessee
State University, USA; Haremaya University, Ethiopia; University of Ballarat, Australia. EXTERNAL ACTIVITIES

Biology
We published a study on the saproxylic beetle fauna on old
oaks (Quercus spp.) with the aim to find a spatial scale at which
density of old oaks best explained the presence of species in a
landscape. Finding such a spatial scale is important for conservation of biodiversity in oak-rich landscapes. Several projects
with similar focus, but different approaches for sampling and
analyses, are currently running.
In some of these spatial projects, we used a new pheromone-trapping method (where the males are attracted to a
substance equivalent to the female pheromone). In 2012 we attempted two additional pheromone systems: a moth associated
with large deciduous trees, and a group of moths in grassland
(burnet moths), that are potential indicator species for monitoring biodiversity.
Another promising line of work involved species dependent
on, or promoted by, forest fire.

Monitoring of species is an important part of detecting
environmental changes. Per Milberg, Lars Westerberg and
Karl-Olof Bergman were involved in a national evaluation of
monitoring programs in semi-natural grassland, and Per Milberg in a feasibility study for monitoring of agricultural weeds
(both commissioned by the Board of Agriculture), and Lars
Westerberg has an appointment as monitoring analysis expert
(the Environmental Protection Agency). Karl-Olof Bergman is
involved in a national monitoring program for biodiversity in
semi-natural grasslands. Heidi Paltto has been invited to talk to
staff members of authorities, and to give a course.
Our staff presented research for students and teachers from
secondary schools in the county at the Popular Science Day,
arranged by IFM. We have also been involved in presentations
for the public arranged by the university, and have guided study
visits from primary and secondary schools.
HIGHLIGHTS
Håkan Lättman presented his PhD thesis “Studies on spatial

was promoted to docent (associate professor).
Since 2010 Kolmarden is engaged in the LIFE project SAMBAH (Static Acoustic Monitoring of the Baltic Harbour porpoise; www.sambah.org), which aims at, by using 300 passive
acoustic data loggers, monitoring harbour porpoises in the Baltic Sea. Kolmarden is the international coordinator. The project
is now in its second year of data collection; it will be completed
in May 2013. The final report will be issued in December 2014.
Kolmården was also engaged in the 3-year EU-project, called
EUZooS-XXI, (www.euzoos-xxi.org). It was finished in September 2012. It focussed on four important conservation topics:
invasive alien species, endangered species, biological diversity
and ecological connectivity. Representatives from the general
public were invited and asked to produce concrete suggestions
how these subjects could be presented to the zoo visitors. At
Kolmarden this resulted in a new animal exhibit, called “Madagascar”, where three lemurs represented the island’s unique,
critically endangered fauna. A rich variety of information was
developed around the exhibit, e.g. via large touch screens and
daily oral presentations by zoo educators.
Kolmården’s engagement in the LiU Masters program
”Applied Ethology and Animal Biology” continues, with several
course parts carried out in the zoo, e.g. the entire 7hp course

several projects concerning the genetics and evolution of
landrace crops and agricultural history with particular attention
to crops cultivated in Fennoscandia. Both genebank material
and seed samples from historical collections are used for the
studies and both neutral markers and functional genes are
investigated to explore both population genetic structure and

Kristina Blomqvist as First Research Engineer, Nils Forsberg as
a PhD student and Hugo Oliveira as a post-doctoral researcher.
The LTP group has established an efficient system for
production of plant lipid transfer proteins. We have also
identified novel Arabidopsis phenotypes showing a role for
LTPs in seed development.
The Historic Seed Group has in collaboration with
researchers at INRA Clermont-Ferrand published a worldwide screen of a nutrient content gene in wheat in Theoretical

Research in the Sensory and Behavioral Physiology Group
focuses on odor structure-activity relationships, that is, on determining the properties of stimulus molecules that are critical
for the interaction with an olfactory receptor and thus for the
odor quality they evoke. A second research topic concerns correlations between chemosensory performance and neurobiological and genetic properties such as the size of olfactory brain
structures or the size of the olfactory receptor repertoire. With
both topics, a comparative approach including human subjects
and a variety of animal models is employed.

Master’s student Nellie Linander gearing up for her studies on olfactory
sensitivity in honeybees, performed at the Centre for Research in Animal
Behaviour at the University of Exeter, England
HIGHLIGHTS
Matthias Laska and one of his students were able to demonstrate that mice are extraordinarily sensitive to the odor of
aliphatic carboxylic acids, substances known to be part of
their body odor. The mice detected concentrations as low as 3
ppt (parts per trillion) and displayed significant correlations
between olfactory sensitivity and molecular structural features
of the odorants such as length or branching of the carbon chain
(Güven and Laska 2012. PLoS ONE 7: e34301).
In collaboration with the Centre for Research in Animal Behaviour at the University of Exeter (England), Nellie Linander
showed that honeybees are able to detect the odor of amino
acids, important constituents of floral nectar, at millimolar
concentrations (Linander, Hempel de Ibarra, and Laska 2012.
Chem. Senses 37: 631-638).
Josefin Arvidsson succeeded in training the Asian elephants
at Kolmården zoo to cooperate in a food-rewarded olfactory
discrimination test, thus adding yet another species to the
comparative studies on olfactory performance performed by
the group. She found that elephants are even faster than dogs,
mice, and rats in learning new olfactory tasks (Arvidsson,
Amundin, and Laska 2012. Physiol. Behav. 105: 809-814).
In collaboration with the Instituto de Neuro-Etologia of the
Universidad Veracruzana (Mexico), Pia Katrine Løtvedt demonstrated that spider monkeys are highly sensitive to the typical
“green odors” emitted by young leaves. Further, she found that
the number of functional olfactory receptor genes are poor
predictors of olfactory sensitivity in primates (Løtvedt, Murali,
Hernandez Salazar, and Laska 2012. Pharmacol. Biochem.
Behav. 101: 450-457).

Molecular chaperones. Folding in vivo is for many proteins
assisted by several protein factors such as molecular chaperones. Although proteins can fold spontaneously the chaperones
suppress aggregation during folding and increase the yield. In
our research we aim to gain insights into the mechanism of
chaperone function that is essential for the understanding of
the folding mechanism and prevention of misfolding.
Misfolding diseases represent a large collection of diseases.
This group includes for example the prion diseases CreutzfeldtJakob disease and mad cow disease; the amyloid diseases such
as Alzheimer’s disease and familial amyloidotic polyneuoropathy (Skellefteåsjukan). All these diseases are connected to a
specific protein that misfolds into alternate conformations and
often forms aggregates. We are working with proteins involved
in all of the mentioned folding diseases. Our objectives are
also to inhibit the formation of the toxic species of amyloid and
prion diseases by using different strategies including smallmolecule binding and interactions with molecular chaperones.
Summary of activities
The research branch of Chemistry, cover all traditional areas of
chemistry. The major research programs Protein Chemistry,
Molecular Biotechnology and Organic Chemistry all have a
strong focus on Molecular Life Science and Chemical Biology. Research activities in Analytical Chemistry, Inorganic
Chemistry and Physical Chemistry are led by senior staff,
often in co-operation with other researchers in the department
and with other research programs at the University. 18 PhD
students have been enrolled and 4 PhD Thesis and 1 Lic Thesis
were defended at the department during 2012.The research in
the different research divisions are presented in the following
sections.

Activities
The general objective of our research in protein chemistry is to
understand different important aspects of the protein folding
process. This also includes misfolding and related diseases as
well as conformational changes associated to protein-protein
interactions and protein adsorption to solid surfaces.
A major goal of protein engineering is the design of stabilized protein variants for use in many applications. In this
project we use several strategies based on experience from our
folding studies to stabilize the structure of our model protein
carbonic anhydrase. Engineered proteins with varying stability and different surface structure are also employed to study
the interaction with solid surfaces, a phenomenon that is very
important in many biotechnological applications.

proteins ultimately misfold into cross-beta-sheet structure of amyloid fibrils.

Thiopurine methyltransferase (TPMT) is a polymorphic
enzyme and a key enzyme in treatment of childhood leukemia
and inflammatory bowel diseases such as Crohn’s disease. TPMT is one of the few classical examples of pharmacogenetics
where the dosages of medical drugs are directly dependent on
the polymorphism of the enzyme.
In collaboration with Department of Clinical Pharmacology
at University Hospital in Linköping mutants of different
variants are engineered and biophysically characterized, using
a repertoire of techniques such as enzyme activity measurements, circular dichroism, fluorescence and differential scanning calorimetry .
In parallel we are also screening conditions to crystallize the
various variants.

Activities
The research activities in molecular biotechnology are focussed
on detailed characterizations of protein structure and dynamics at the molecular level. The role of protein interactions for
understanding a variety of biological functions are addressed
in different projects. The results which are gleaned from our
studies of these fundamental biological phenomena are also
utilized in projects, which aim at efficient diagnosis and novel
strategies for treatment of some human diseases.
The protein misfolding disease ALS: The mis-folding and
intracellular aggregation of the protein superoxide dismutase is
strongly coupled to the neurodegenerative disease ALS. To find
the molecular basis for ALS we perform a detailed characterization of the structural and dynamical effects of a large set of
different ALS-associated mutations in the gene for CuZnSOD.
Therefore, we have used chemical cross-linking, analytical
ultra-centrifugation and hydrogen/deuterium-exchange experiments to unravel the effects of the mutations on the dynamics
of the protein.
Protein-surface Interactions. Enzymes are of increasing
use in biotechnological applications. Regardless of the application, the enzymes will always encounter surfaces and this will
often lead to that the enzyme activity is lost. It has been a long
standing perception that ”soft” proteins are proteins that bind
to, and unfolds at, surfaces even when there are no apparent
attractive force between the protein and the surface. There is
however little knowledge about which features of a protein that
dictates whether a protein will behave as a “soft” protein or a
“hard” protein, although the physical stability of the protein is
believed to play a crucial part. In order to discriminate between
the importance of thermodynamic stability and kinetic stability we have engineered protein variants with these properties
separated. Our aim is to pinpoint which feature is the most
important so that the correct modifications can be performed
on proteins that are to be used in various biotechnological
applications.
Stabilization of Carbonic anhydrase. At this time there is a
consensus view that the concentration of CO2 in the atmosphere is the major contributor to increasing global warming and
much effort is directed to find methods for carbon capture and
sequestration (CCS). However, no method has thus far proved
to be practically or economically feasible. Since the natural
function of carbonic anhydrases is to facilitate the removal of
carbon dioxide from the blood it has been suggested that carbonic anhydrases can be used as biological catalysts in bioreactors
designed for capturing CO2 from various gas streams. However, there are no naturally occurring carbonic anhydrases that
have high enough stability to be used in such a bioreactor. We
are therefore currently working on the design of engineered
human carbonic anhydrases with increased stability which
can then be used as catalysts in enzyme based bioreactors for
carbon capture and sequestration.
Functionalization of nanoparticles by peptide design: Earlier studies have given us a firm knowledge about the
structure of and dynamics in proteins upon adsorption to solid
surfaces. Recently we have unraveled fundamental principles
that govern the formation of helical structure on silica nanoparticles, which is important in the development of devices that
interact with biological systems.
Alzheimer’s disease: The aim of this project is to perform
detail studies of the molecular origins of Alzheimer’s disease
(AD). The aggregation process of the amyloid β peptide (associated with AD) is studied by using Drosophila melanogaster
as a model organism, in parallel with biophysical studies. The
challenge is to identify and characterize toxic species as well
as to study the influence of cellular factors on the toxicity. This
knowledge will then be used to test the effect of anti-aggregation agents in vitro as well as in vivo.
Lysozyme amyloidosis: Misfolding and aggregation of lysozyme are associated with lysozyme amyloidosis where abnormal depositions of aggregated protein are found in organs
such as the liver, spleen and kidney. By expressing lysozyme
in Drosophila melanogaster we can study the aggregation of
these proteins in a complex multicellular environment and
look into the role of specific cellular factors and pathways in the
pathogenesis caused by lysozyme misfolding and aggregation.
Results from studies using this Drosophila model suggest that
the onset of familial amyloid disease is linked to an inability of
the quality control system in the cell to completely degrade the
amyloidogenic lysozymes prior to secretion, resulting in secretion of these destabilised variants, thereby leading to deposition
and associated organ damage.
Rational Enzyme mining: Enzymes are biological catalysts that
find their use in a large number of biotechnological applications and enzyme based industrial processes are expected to
increase in the near future. One central concern in order to
realize the promise of industrial biotechnology is then to find
new enzymes that are active and stable at the conditions of
interest. In this respect microorganisms are an ideal source of
novel enzymes since they can survive and propagate in many
environments. However, to be able to screen full microbial
communities for new enzymes methods that is independent of
pure culturing needs to be developed. We are currently working
on the development of such methods to mine for new enzymes in methanogenic microbial communities in experimental
biogas reactors.

Protein-protein interactions are intrinsic to virtually every
cellular process. We are studying the interaction of the cellular receptor tissue factor (TF) with the coagulation factors VII
(FVII) and X (FX) that is the key step in the initiation of blood
clotting and thrombus formation. The information output from
this project will directly be used in drug design of therapeutic
agents that can intervene in the association process of FVII and
FX to TF.

Enzymatic enhancement of sludge digestibility: As partners
of the centre of excellence in biogas research, recently established at LiU with support from the Swedish Energy Agency, we
are investigating the possibilities to enhance sludge digestibility with enzymes for increased biogas production. The aim
of the research is to determine whether enzyme addition de
facto is a feasible method to increase biogas production. For
this, it is necessary to monitor the fate of added enzymes by
determining the activity, modification and lifetime of each type
of added enzyme at the conditions that would prevail in a real
life process, rather than simply observing the effect in biogas
production. This can then be used to correlate enzyme activity
to e.g. metabolite turn-over and possible inactivation mechanisms of added enzymes. This will also give information about
e.g. which of the many commercially available enzymes which
are the most suitable for the intended process.
Bacterial and immunological responses in infectious
disease. The human Ro52 protein is an autoimmune target
in Sjögren’s disease, and involved in the production of fetal
antibodies in pregnant mothers. We have characterised the
interaction of the disease-related antibodies and are currently
characterizing the subdomains of Ro52 and their interactions
on a molecular level.
Our most recent results show that patient autoantibodies that
hinder ubiquitination interfere with the E2-binding surface of
the E3-active RING domain of Ro52. Taken together with our
previous studies, we can now propose an action model for the
entire Ro52 protein (Fig III, below) MexR is a DNA_binding
protein that regulates the expression of the Pseudomonas
Aeruginosa efflux pump, and a target for antibiotic resistance
mutations leading to multi-drug resistance. We have described
the biophysical and molecular basis for resistance and are currently evaluating their implications on structure.
globule structure, perhaps a prerequisite for its high-affinity
binding to a range of biologically important target proteins. A
range of protein interactions are currently being screened on a
structural level.
Structural biology in cancer and infectious disease The
group of Maria Sunnerhagen is currently describing a series of
intrinsically disordered interactions between the c-Myc transactivating domain and its regulatory co-partners, including
Bin1 and TBP, using both NMR and crystallography. The Ro52/
Trim21 regulatory network including E2 ligases Ubch6 and
Ubch8 is addressed using a range of biophysical and biochemical techniques. In our Pseudomonas Aeruginosa project, aimed
to investigate principles for novel antibiotics, several novel protein structures have been determined and molecular dynamics
simulations reveal novel principles for how mutations result in
antibiotics resistance
Regulation of kinase activity. Eph proteins are involved in
developmental processes such as cell migration, angiogenesis
and axon guidance and in the adult organism they have been
implicated in certain cancers. The crystal structure of the
kinase domain of EphB2 as well as those of other Eph proteins
suggests that the ground-state cannot be catalytically active.
Our working hypothesis is that a low-populated “excited” state
is responsible for catalysis and we have shown that the protein
exchanges between the ground-state and something else on the
millisecond time-scale. We are currently using NMR spectroscopy and x-ray crystallography to further study the interplay
of structure and dynamics for this unusual mode of enzyme
regulation.

As a first instance we are synthesizing oligothiophenes that can

Synthesis of potential protease inhibitors: Proteases are
enzymes capable of restructuring peptides and proteins by specific hydrolysis and are therefore powerful mediators for health
and disease. There are five different classes of proteases, classified according to the most significant functional group in the
active site of the enzyme. Design and synthesis of inhibitors
and screening for efficient and selective inhibitors of key proteases have become an attractive and powerful course for new
drug development. This is an area of fundamental importance
to the pharmaceutical industry. Structure based drug design
has been used in the search for potent and selective drug candidates. An important part of this is to find the minimum necessary chemical features for binding to a particular protease.
Methods for screening of potential inhibitors are available and
it is possible to screen large libraries of single compounds to
identify lead compounds. Design and synthesis of inhibitors
have been studied against the following proteases: HIV-1 protease, Hepatit C protease, Malaria parasite proteases, Thrombin
and γ–Secretase (Alzeimers disease). The research projects are
done in collaboration with the University of Stockholm, BMC,
Uppsala and Medivir AB, Huddinge.

tools that can be used for real time in vivo imaging of biological
events from the nanoscopic level (biomolecules and cells) to
the macroscopic level (organs and body). Secondly, we are also
investigating if similar molecular scaffolds can be utilized as
therapeutic active agents towards distinct pathological processes.
Furthermore, we are developing electro-active oligothiophene
derivatives that can be combined with defined biological template molecules, such as amyloid fibrils, to generate materials
that can be implemented with in research areas such as nanobioelectronics. Though a multidisciplinary collaboration with
other researchers at IFM and ITN, we are aiming at develop
novel materials that can be used for electronic release of pharameuticals, and devices that can stimulate and record cellular
activity in complex environments.

Activities
The research projects concern computational-chemistry studies
of nanostructures, functionalized nanoparticles, dye-sensitized
metal oxide solar cells, electron transfer processes, heterogeneous catalysis, and water and hydrogen bonding phenomena. We thereby apply quantum-chemical computations and
molecular-dynamics simulations using national supercomputer
facilities to address these fundamental issues in surface science
and atmospheric chemistry.
Nanoparticles exhibit many unique properties. We model
crystallites of materials such as ZnO, TiO2, RuO2 and Gd2O3
and quantum dots of GaN, which are of interest in applications
ranging from nanomedicine to optoelectronics. In particular
we design novel nanocompunds by functionalising metal oxide
nanoparticles using organic adsorbates. One such example
is the dye-sensitised solar cell, where organic molecules are
chemisorbed at a nanostructured metal-oxide surface (ZnO,
TiO2). Catalytic reactions at metal-oxide surfaces (RuO2) are
also studied, where we are developing ab initio MD methods
that are useful for elucidating the mechanisms of surfacecatalyzed reactions.

Another research theme concerns hydrogen bonding, where
we are elucidating the phase transitions and proton-ordering
phenomena involving water clusters, liquid water, ice and
clathrate crystals. These investigations are of importance for
understanding for example the properties of liquids, environmental processes occurring in the atmosphere, and CO2 emission from the tundra.

The research in inorganic chemistry at IFM is mainly focused
on colloidal synthesis and characterisation of (i) magnetic
metal oxide nanoparticles (e.g. Gd2O3) for magnetic resonance
imaging; (ii) chemical or electrochemical synthesis of semiconducting nanoparticles, e.g. ZnO, CuO, Cu, as sensing material

The above projects are pronounced interdisciplinary with collaboration partners both within and outside IFM.

(NCT). We have found that small nanocrystals of cubic Gd2O3
produce significantly shorter T1 relaxation times than the
conventional gadolinium containing chelates normally used
in examination of patients. A possible explanation of the effect
is the higher density of magnetic active ions in a nanoparticle
compared to that of a bulky chelate providing access of only a
single water molecule to the magnetic central atom.

Activities
Research in Analytical Chemistry is focused on analytical
carbohydrate chemistry and studies structures of biologically
active carbohydrates from pathogenic bacteria. Of particular
interest are the exclusively human pathogen non-typeable Haemophilus influenzae (NTHi) and Helicobacter bizzozeronii,
which normally colonizes cats and dogs. Humans potentially
acquire gastric infections as a consequence of direct contact
with these animals. NTHi causes otitis media and both acute
and chronic lower respiratory tract infections in small children. The potential of both NTHi and H. bizzozeronii to cause
disease depends upon their surface expressed carbohydrate
antigen, lipopolysaccharide (LPS).
The heterogeneity and structural complexity of LPS from pathogenic bacteria pose significant analytical challenges. Typically, structural profiling involves analyses by chemical, nuclear
magnetic resonance (NMR) and mass spectrometric (MS)
methods. Electrospray ionization mass spectrometry (ESI-MS)
has played an increasingly important role in the characterization of LPS. CHEMISTRY-Highlights

Figure. Survival curves for ”Alzheimer flies” treated (dashed line) and those
not treated with curcumin. The flies that were administered curcumin
lived longer and were more active. The scientists identified an accelerated
formation of amyloid plaque in the treated flies, which seemed to protect the
nerve cells. On the right we see microscopic images of neurons (blue) and
plaque (green) in the fruit fly’s brain. The study strengthens the hypothesis
that a curcumin-based drug can contribute to toxic fibrils being encapsulated (bottom left of the figure).
IV. A study from Nilsson lab in collaboration with Hammarström and with colleagues at the University Hospital in Zürich
(Aguzzi) tested luminescent conjugated polymers, or LCPs,
on organotypic live tissue sections from the brains of mice
that had been infected with prions. The results show that the
number of prions, as well as their toxicity and infectibility,
decreased drastically. This is the first time anyone has been
able to demonstrate the possibility of treating illnesses such as
“mad cow” disease and Creutzfeldt-Jacobs with LCP molecules.
The course of prion disease is relentless when the prions fall to
pieces and replicate at an exponential rate. When researchers
inserted the LCP molecules into their model system, the replication was arrested, through stabilizing the prion aggregates –
which is a new concept in treating prion disease.

Alzheimer’s disease, which is characterized by the accumulation of sticky amyloid-beta and Tau protein amyloid fibrils.
Linköping researchers wanted to investigate how the substance
affected transgenic fruit flies (Drosophila melanogaster),
which developed evident Alzheimer’s symptoms. Flies shwoed
enhanced activity, deceased neurotoxicity and lived up to 75%
longer when treated with curcumin. However, surprisingly
the amount of amyloid in the brain or eyes did not decrease.
Curcumin did not dissolve the amyloid plaque; on the contrary
it accelerated the formation of mature fibrils by reducing the
amount of their precursor forms, known as oligomers.
The study hence, indicates that it is the initial stages of fibril
formation and fragments of the amyloid fibrils that are most
toxic to neurons and that curcumin accelerated this conversion
step.
The article “Curcumin promotes A-beta fibrillation and
reduces neurotoxicity in transgenic Drosophila”. was published in PLoS One (2012). Ina Caesar, Maria Jonson, K. Peter,

The Material Physics Area is the largest research unit of the
Faculty and is internationally recognized as a strong research
environment. It engages ~150 persons, including over 60 PhD
students. The research is of a basic experimental character, but direct
collaboration with industry is essential in many projects. Theoretical modelling is a natural part of many projects.
The research activities include growth of a variety of material
structures with different techniques, mainly PVD, CVD and
sublimation-based. The materials studied span a broad field,
such as metallic thin films, semiconductor materials, nanostructures, and organic structures.
We operate several advanced laboratories; mostly in clean
room environment. The characterization techniques include
electron microscopy (SEM, TEM, FIB, EELS, PL, CL) and surface studies (ARUPS, STM, AFM, XRR, ERDA, XPS), partly at
external synchrotron radiation facilities, but also extensively optical, transport and magnetic resonance techniques. Collaboration with foreign laboratories is typical for all research groups;
in fact most published papers have international co-authors.

In the area of ZnO-based materials, several topics were addressed. We have continued our studies of exciton dynamics and
exciton-photon coupling in bulk and nanostructured ZnO. We
have also initiated investigations of non-linear optical and plasmonic effects in ZnO NWs. In bulk ZnO, signatures of excitons
bound to isoelectronic centers - an important class of excitons
and defects that have so far hardly been investigated in ZnO,
were provided. Impact of various intrinsic defects on p-type doping of ZnO via ion implantation with phosphorous and nitrogen
were also examined.
In 2012, we have conducted detailed studies of spin-dependent
properties of self-assembled InAs/GaAs QD, QD molecules and
rings. Special attention was paid to understanding the physical
mechanism for spin injection, spin relaxation and spin detection.
For dilute nitrides like Ga(In)NAs and Ga(Al,In)NP, the
presence of harmful residual defects is still one of the major
obstacles preventing the materials from practical applications in
photonics and optoelectronics. In 2012, we have continued our
experimental efforts to identify point and interfacial defects that
are responsible for deteriorating optical quality of the materials. We have also initiated new research activities on GaP/GaNP
core/shell NWs. Great potential of these structures as nano-sized
light emitters was demonstrated based on the observation of
intense emission from a single NW at room temperature. Our
current efforts are devoted to improving optical efficiency of the
NWs via optimization of their structural design and material
quality.
We have also been actively involved in the education program
for undergraduate students. During the year, the courses in
“Semiconductor Technology” (TFYA39) and “Perspectives on
Physics” (TFFM12) were given.
HIGHLIGHTS
Room-temperature electron spin amplifier based on Ga(In)NAs alloys
The first experimental demonstration of a spin amplifier at
room temperature is presented. An efficient, defect-enabled
spin amplifier based on a non-magnetic semiconductor Ga(In)
NAs is proposed and demonstrated, with a large spin gain (up to
2700% at zero field) for conduction electrons and a high cut-off
frequency > 1 GHz. [Adv. Mater. 25, 738 (2013)]
We conduct scientific research on electronic, magnetic and optical properties of semiconductor materials and nanostructures.
The materials systems under study in 2012 include: (i) advanced
spintronic materials based on II-VI and III-V semiconductors;
(ii) ZnO-based materials and nanostructures; (iii) self-assembled
InAs/GaAs quantum dot (QD) nanostructures; (iv) dilute
nitrides; and (v) GaP/GaNP core/shell nanowires (NWs). The
research has been carried out mostly through close collaborations with many groups worldwide. Our aim is to obtain a better
understanding of fundamental physical properties and a good
control of materials properties, and to fully explore functionality of the studied materials for applications in future generation
micro- and nano-electronics and photonics, spintronics, as well
as in potential multifunctional devices and systems.
In the area of spintronic semiconductors, we have continued
and extended studies of our recently discovered room temperature spin-filtering in a non-magnetic semiconductor Ga(In)NAs.
The focus has been on development of room-temperature spin
amplifier and spin detector based on Ga(In)NAs. We have also
studied magnetic interactions in coupled CdSe/ZnMnSe QD
structures. Fig.1 A schematic picture of the demonstrated defect-engineered spin
amplifier.
Evidence for coupling between exciton emissions and surface plasmon in Ni-coated ZnO NWs
We show that coating ZnO NWs with a transition metal, such
as Ni, can increase the efficiency of light emission at room
temperature. Based on detailed structural and optical studies,
this enhancement is attributed to energy transfer between nearband-edge emission in ZnO and surface plasmons in the Ni film
which leads to an increased rate of the spontaneous emission. It
is also shown that the Ni coating leads to an enhanced non-radiative recombination via surface states, which becomes increasingly important at low measurement temperatures and in annealed
ZnO/Ni NWs. [Nanotechnology 23, 425201 (2012)]

Dynamic nuclear polarization and its effect on electron
spin relaxation and dephasing in InAs/GaAs QDs
Efficient upconvertion of photoluminescence via twophoton-absorption in bulk and nanorod ZnO
Electron spin dephasing and relaxation due to hyperfine
interaction with nuclear spins is studied in an InAs/GaAs QD
ensemble as a function of temperature up to 85 K, in an applied
longitudinal magnetic field. The extent of hyperfine-induced
dephasing is found to decrease, whereas dynamic nuclear
polarization (DNP) increases with increasing temperature. We
attribute both effects to an accelerating electron spin relaxation
through phonon-assisted electron-nuclear spin flip-flops driven
by hyperfine interactions, which could become the dominating
contribution to electron spin depolarization at high temperatures. [Appl. Phys. Lett. 100, 143105 (2012)]
Efficient upconversion of PL from donor bound excitons is
revealed in bulk and nanorod ZnO and attributed to two-photonabsorption (TPA) and two-step TPA (TS-TPA) processes. The TSTPA process is found to occur via a defect/impurity (or defects/
impurities) with an energy level (or levels) lying within 1.14-1.56
eV from one of the band edges, without involving photon
recycling. One of the possible defect candidates could be VZn. A
sharp energy threshold, different from that for the corresponding one-photon absorption, is observed for the TPA process and
is explained in terms of selection rules for the involved optical
transitions. [Appl. Phys. B: Lasers and Optics 108, 919 (2012)]
Mechanism for radiative recombination and defect properties of GaP/GaNP core/shell NWs
Zeeman splitting and dynamics of an isoelectronic bound
exciton near the band edge of ZnO
Recombination processes in GaP/GaNP core/shell NWs grown
on a Si substrate by molecular beam epitaxy are examined using
a variety of optical characterization techniques, including cwand time-resolved photoluminescence (PL) and optically detected
magnetic resonance (ODMR). Superior optical quality of the
structures is demonstrated based on the observation of intense
emission from a single NW at room temperature. This emission
is shown to originate from radiative transitions within N-related
localized states. From ODMR, growth of GaP/GaNP NWs is also
found to facilitate formation of complex defects containing a P
atom at its core that act as centers of competing recombination.
[Appl. Phys. Lett. 101, 163106 (2012)]
Sub-millisecond dynamic nuclear spin hyperpolarization
in a semiconductor: A case study from PIn antisite in InP
ODMR is employed to identify key factors governing DNP in a
semiconductor. We demonstrate that the extent of DNP can be
efficiently controlled by varying lifetime of the localized electrons
that transfer spin angular momentum to nuclei. The ultimate
speed of a DNP process, on the other hand, is determined by the
strength of hyperfine interaction that drives DNP. We show that
about 50% nuclear spin polarization of a PIn antisite in InP can
be achieved by shortening electron lifetime within a remarkably
short time (<0.1 ms), see Fig.2, due to strong hyperfine coupling.
[Phys. Rev. B 86, 205202 (2012)]
Comprehensive time-resolved PL and magneto-optical measurements are performed on a bound exciton (BX) line peaking at
3.3621 eV (labeled as I*). Though the energy position of I* lies
within the same energy range as that for donor bound exciton
(DX) transitions, its behavior in an applied magnetic field is
found to be distinctly different from that observed for DXs. An
exciton bound to an isoelectronic center with a hole-attractive
local potential is shown to provide a satisfactory model that can
account for all experimental results of the I* transition. [Phys.
Rev. B 86, 235205 (2012)]

Hard coatings:
The thermomechanical properties of nanostructured reactive arc
evaporated ceramic materials are studied in model systems that
include a miscibility gap. Special interest is paid to the kinetics of the decomposition process in hard coatings and how it is
influenced by the environment. Here we use high energy SAXS,
and DSC as tools to in situ study the formation of nm-sized
particles within the solid solution. STEM and 3D-atom probe in
combination with phase field and ab-initio calculations are used
to further advance the understanding. An example of a reconstructed 3D-atom probe image of a multilayer is given in the
figure below, i.e nanocandy.
In addition the microstructure evolution of alloyed cathode surfaces are also studied.

General Information
The division of Nanostructured Materials was established 1 April
2007 as a response to several research centers being granted at
that time (i.e. Vinnova-FunMat, VR-LiLi-NFM, and SSF-MS2E).
In 2009 SSF granted the group an additional Material Science
program called MultiFilms and 2010 an Erasmus-Mundus
graduate school, DocMase, with support from EC for 20 students was added. Naturally most of the Nanostructured Materials group’s research activities are related to these centers and
programs.
The scientific aim of the group conforms to the material science paradigm: understanding of the synthesis, microstructure
evolution, and material properties of nanostructured materials of
industrial interest.

Introduction
The Plasma & Coatings Physics group is a division at the Department of Physics, Chemistry and Biology (IFM), Linköping
University, Sweden. Our overall goal is to contribute towards addressing challenges of contemporary materials science and technology through the synthesis of novel films and nanomaterials.
To realize this goal, we employ innovative processes which allow
for the generation of plasmas with unique properties as well as
control of the material synthesis at the atomic level. Through a
combination of advanced experimental and theoretical tools we
seek to understand the process-plasma-material interactions and
gain insight into the knowledge-based synthesis of functional
films and nanomaterials.
Scientific Highlights in 2012
Nanoparticles: Synthesis & characterization
Our novel high power pulsed-plasma based method for synthesizing nanoparticles (particles with sizes in the range of a few to
hundreds of nanometers) was developed further during 2012.
The method allows for the synthesis of nanoparticles of a wide
range of materials with a narrow size distribution. The past year,
we have focused on the materials (silver and copper) and how
the process parameters and the geometry of the experimental
set-up affect the nanoparticle growth. It was found that the different geometries of the experimental set-up greatly affect e.g.
the sizes of the nanoparticles. To get a fast response on the mass
of the synthesized and collected nanoparticles when the process
parameters are changed, research on using a quartz crystal
microbalance (QCM) for this purpose was initiated. Preliminary
results show that the QCM can be a valuable tool to determine
“sweet spots” for the process (see Fig. 1).

Fig. 1. Deposited mass of nanoparticles as a function of pulse frequency for
different peak currents. The pulse width was 30µs and the pressure 0.8 Torr.
A new compact vacuum system for the synthesis of nanoparticles was procured during the year. It will be devoted to the synthesis of oxide nanoparticles, e.g. copper and zirconium oxides,
which will find applications in projects that are run in collaboration with other groups at the university.
Work on a computer simulation of the nanoparticle growth in
a highly ionized plasma was initiated. The computer model will
allow us to see how the plasma parameters will affect the collection efficiency of ionized material to the nanoparticles, and will
help us to understand the fundamental processes we observe in
the experiments. A manuscript is planned to be submitted during the first half of 2013.
Research on core-shell nanoparticles was continued with a
major re-design of the synthesis chamber. We now have the
opportunity to accurately sift ready-made particles through our
coating zone. This allows us to study the coating of nanoparticles
before we combine the processes to synthesize both the core and
the shell in a continuous process.
During the year, two manuscripts were submitted to peerreviewed journals.
Control of film nucleation and growth using ionized pulsed vapor
fluxes
We have used pulsed, ionized fluxes generated by a HiPIMS
discharge to deposit Ag films on SiO2 substrates. We have found
that the time domain of the deposition flux (controlled by the
pulsing frequency), the instantaneous vapor arrival rate and the
energy of the film forming species (control by the pulse energy)
enable one to tailor film nucleation and growth, manifested by
the changes in the film thickness required for the completion of
the film coalescence (Fig. 2).
Reference: D. Magnfält et al., “Time-domain and energetic
bombardment effects on the nucleation and coalescence of thin
metal films on amorphous substrates”, submitted for publication.

thickness at pulse energy, Ep, values of 20 (squares), 40 (circles) and 60 mJ
(triangles). (b) Dependence of coalescence completion thickness on deposition rate during pulsed (Ep=20 mJ, f=50 Hz/squares) and continuous (DCMS/
circles) deposition. (c) Effect of pulse energy (at constant f=50 Hz) on the coalescence completion thickness. In all cases coalescence completion thickness
values calculated from the intrinsic stress measurements are plotted.
Atomistic mechanisms for stress generation in physically
vapor deposited films
We have studied the stress evolution in Mo films grown by
HiPIMS. We have found that, depending on the energetic bombardment encountered by the growing film (controlled by the
process conditions), films with intrinsic stresses ranging from
highly compressive to slightly tensile are obtained. No correlation between the stress and the stress-free lattice parameter has
been observed (Table I) indicating no changes in the concentration of intra-grain point defects. On the contrary, compressive
stress generation is associated with increase of the film mass
density (Table I). Based on these results, we have concluded that
compressive stresses are generated via grain boundary densification through incorporation of film forming species. Atomistic
mechanisms that lead to diffusion of film forming species into
grain boundaries have been suggested.

to insertion of adatoms into grain boundaries and compressive
stress generation in physically vapor deposited film”, in final
preparation.

Synthesis of carbon-based thin films using HiPIMS
We continued to explore the potential of HiPIMS for the synthesis of carbon based thin films in the year 2012. We developed
a HiPIMS based process for the synthesis of hydrogenated
amorphous carbon (a-C: H) thin films. The process is based on
the hybrid arrangement of HiPIMS and DCMS, whereas the
film synthesis is performed using a hydrocarbon precursor gas
(acetylene) mixed with argon. We have found that the a-C:H thin
films with low H content (about 10%) can be grown at about
ten-fold higher deposition rate as compared to those deposited in
pure argon ambient using an acetylene fraction of 5% in the gas
mixture. The films, along with low H content, exhibit high hardness (more than 25 GPa) while the mass densities of the films in
the order of 2.32 g/cm3 are obtained (Fig. 4). Reference: A. Aijaz et al., “High-rate deposition of hydrogenated amorphous carbon thin films using high power impulse
magnetron sputtering”, in preparation.

Tilt of the columnar microstructure in off-normally deposited films using
highly ionized vapor fluxes

material physics
We have investigated the tilt of the columnar microstructure
in Cu and Cr films deposited off-normally from highly ionized
fluxes generated by a HiPIMS discharge. We have found that
the film columns are positioned closer to the substrate normal
as the ionization degree of the incident vapor increases (Fig. 3).
This correlation between column tilting and degree of ionization is, however, valid only at certain kinetic conditions during
growth (Cu but not Cr films at room temperature), indicating
that the film morphology during the nucleation stage also affects
the resulting column tilt (Fig. 3). A phenomenological model
that explains, qualitatively, the column tilt accounting for atomic
shadowing at different nucleation characteristics has been suggested. Reference: V. Elofsson et al., “Tilt of the columnar microstructure in off-normally deposited thin films using highly ionized
vapor fluxes”, submitted for publication.

material physics
Fig. 4. Hardness, mass density and the H content of the a-C: H thin films
grown using 5% acetylene in the gas mixture and the equal fractions of
HiPIMS and DCMS powers. The total average power used was 50 W while the
total pressure of 2 Pa was used.
We have used HiPIMS to synthesize Al-Si-O wear-resistant
antireflective coatings. Broad band anti-reflective multilayer
coatings require the use of a low-index material at the top
position. Normally SiO2 is used which exhibits sufficiently low
refractive index (~1.5 at 550 nm) yet its low hardness (~10 GPa)
hinders its application in abrasive environments. A strategy to
circumnavigate these limitations is the synthesis of multicomponent materials that combine good mechanical and optical
performance. We synthesize Al-Si-O films seeking to combine
the low refractive index of SiO2 and the relatively high hardness
of Al2O3. HiPIMS is used to enhance film properties, such as
density and hardness. The work is performed in the framework
of the EU project NoScratch (Grant agreement no 286697) in
which our group is one of the RTD performers.
HiPIMS – Reactive Sputtering
Awards 2012
Discharge current behavior in reactive HiPIMS
In a more recent work, we investigated the behavior of the
discharge current in reactive HiPIMS processes of metal-oxides
(Ti-O and Al-O). The investigations were carried out by measuring the ionic contributions of the sputtering and reactive gas
ions (Ar1+ and O1+ respectively), sputtered metal ions (Ti1+
and Al1+) as well as material-dependent properties (secondary electron emission yield and partial sputtering yield), to the
discharge current. The ionized flux of the plasma species, Ar1+,
O1+, Ti1+ and Al1+ was obtained by measuring the time-averaged
and time-resolved ion energy distribution functions using ion
mass spectrometry while the secondary electron emission and
partial sputtering yields were obtained by performing TRIDYN
simulations.
It was found that the observed increase in the discharge current in the oxide mode is due to the substantial contribution of
O1+ ions to the discharge current while the source of these O1+
ions is the sputtering target rather than the gas phase.

The research activities in the Semiconductor Materials Division
cover a broad spectrum, dominated by basic research. The projects are mainly funded by external agencies, partly with direct
industry collaboration. There is a strong international cooperation within most research projects. The present research program can be divided into the following partly overlapping areas:
• Preparation and characterization of epitaxial films and bulk
material of semiconductors with chemical vapor deposition
(CVD), and sublimation techniques, with a strong emphasis
on SiC and III-nitrides. The characterization includes surface
and interface properties, structural properties, optical properties and transport properties.
• Investigation of properties of dopants and defects in a large
variety of semiconductors, including structural as well as electronic properties. The latter covers bulk, surface and interface
defects, with several techniques including laser spectroscopy
and magnetic resonance. • Preparation and investigation of the electronic properties of
semiconductor quantum structures and nanostructures such
as heterostructures, quantum wells, quantum wires and dots,
and superlattices, with various spectroscopic techniques in
several material systems.
• Studies of the electronic structure of III-nitride materials
including defects and doping.
• Fabrication and characterization of graphene on SiC.
• Development of GaN and AlGaN/GaN HEMT structures for
high-frequency power devices and Al-rich AlGaN heterostructures for laser diodes (LDs) and light emitting diodes (LEDs)
in the UV (<400 nm) and deep UV (DUV, <300 nm) spectra
regions.
improved spectroscopy, enhanced thermal conductivity, and
for quantum computing studies.
Research activities in this division during 2012 have produced
73 papers published in high quality international journals, 26
conference proceedings papers with peer review and 3 review
articles/book chapters. During the year, 15 invited talks were
given by the staff at international conferences or symposia. The
researchers of the division are well cited in international journals, the SCI citations of papers cited for the researchers in the
division cover more than 22000 ISI citations.

The turnover for research in our division was about 57.9 MSEK during the period 120101-121231, excluding equipment
grants. The major part of this budget comes from external
sources. The faculty support for research was about 8 MSEK
for the year. External grants originate mainly from the Swedish
Research Council (VR), the Knut and Alice Wallenberg Foundation (KAW), the Swedish Strategic Research Foundation (SSF),
Swedish Energy Agency, European Defence Agency (EDA/
FMV) and EU. In addition there is a strong support from and an
intimate cooperation with several industries, mainly LG Innotek,
Norstel AB and Aixtron AB, and with the Defense Research
Institute FOI. The Division was during 2012 engaged in several European
research projects and Nordic project:
Manga and EuSiC are two large-scale joint multinational
initiatives of leading system houses and research laboratories in
Europe aiming at the development of independent and state-ofthe-art capability in GaN HEMT technology. The goal of EuSiC is
to develop high quality European GaN-Wafer on SiC substrates
for space applications and to create an independent European
supply chain for space technology.
NORLED– The N-Inner project with partners from Sweden,
Denmark, Germany and Norway explores fluorescent silicon carbide for light emitting properties. A paper that describes the new
research was included in the Physica Scripta Highlights of 2012.
This collection celebrates the most influential research published
in the journal from the last 12 months.
LG-Innotek– The project, which is sponsored by LG Innotek
and the State of South Korea, strives to develop uniform epitaxial
layers for power device material on 4” wafers using the chlorinated epitaxial process that has been studied here for several years.
The first phase (three years) of the project has been concluded
and the next phase is about to commence. During the coming
phase the focus will be on reducing the density of structural
defects that are harmful to the device performance and increase
and control the carrier lifetime of the material which is an essential part in the fabrication of bipolar devices.
A major part of the KAW project is devoted to isotope enriched
SiC mainly for improved thermal conductivity. Isotope enriched
SiC layers manifest a number of interesting properties useful for
scientific and industrial applications. Among them is a very narrow linewidth in optical characterization which enables detailed
measurements of defect centers. Another interesting phenomenon of the enriched layers is that they exhibit significantly higher
thermal conductivity due to a reduced isotope scattering process
in the material. We produced a number of isotope enriched
epitaxial layers which we used to measure thermal conductivity on. The measurements told us that we indeed could see a
substantial improvement in thermal conductivity yet we have not

yet been able to firmly establish the magnitude of the increase
as compared to natural SiC. In light of the favorable outcome
of these experiments we managed to secure a larger amount of
enriched precursor gas to continue our experiments. A new reactor which is specially designed to reduce contamination from
foreign isotopes is being constructed.
The SSF project SiC – the Material for Energy-Saving Power
Electronics started in 2012 and is focussed on determining,
understanding and improving material related issues in SiC
epitaxy and gate dielectrics, which today are the limiting factors
for the SiC power device technology. The project includes: (i)
Understanding and control of carrier lifetime limiting defects
in SiC material and devices, (ii) Characterisation and identification of device-critical epitaxial defects, (iii) Investigation novel
alternative gate dielectrics and novel fabrication techniques, (iv)
Develop on-axis and/or low-off angle epitaxy for power device applications and (v) Develop Cl-based epitaxy for high growth rates.
Three PhD students (Remigijus Vasiliauskas, Anders Lundskog, Mengyao Xie) and four diploma works graduated in 2012.
The Division is very active in teaching and has the responsibility
for about 20 undergraduate and graduate courses at IFM.
3. Highlights
Chloride-based CVD growth of Silicon Carbide for
Electronic Applications
A review paper on chloride-based SiC CVD was published in the
highly renowned journal Chemical Reviews, highest ranked journal in the field of multidisciplinary chemistry (the 2011 impact
factor is 40.197). This is the first review of the field of chloridebased CVD for SiC. [H. Pedersen et al., Chemical Reviews 112,
2434 (2012)].
Low temperature CVD of boron-carbon films for neutron detectors
To enable CVD for the production of the novel neutron detectors
based on the isotope 10B suggested by the European Spallation
Source (ESS), novel low temperature CVD routes are needed.
The neutron detectors will be based on aluminum, setting an upper temperature limit of 600°C and preventing the use of BCl3
as boron precursor. We have demonstrated the synthesis of thin,
amorphous, boron-carbon films, with density and stochiometry
close to B4C, at ≤ 600 °C by thermally activated CVD using the
organoborane triethylboron, B(C2H5)3, (TEB) as single precursor. [H. Pedersen et al., Chem. Vap. Deposition 18, 221 (2012)]

A novel high-power pulse PECVD method
A novel plasma enhanced CVD (PECVD) technique has been
developed in order to combine energetic particle bombardment and high plasma densities found in ionized PVD with the
advantages from PECVD such as a high deposition rate and the
capability to coat complex and porous surfaces. Ionized plasma
is generated above the substrate by means of a hollow cathode
discharge sustained in direct current (DC) mode, or in highpower pulsed (HiPP) mode using short pulses of a few tens of
micro second. [H. Pedersen et al., Surf. Coat. Technol. 206, 4562
(2012)]
Growth of semiconductor quality 3C-SiC
Cubic SiC was grown by a sublimation method. Bulk like material demonstrated that the 3C-SiC can reach similar quality like
commercial hexagonal SiC. As an ultimate device property, in a
760 µm thick material the measured carrier lifetime is 8.2 μs,
which is comparable with the best carrier lifetime in 4H-SiC layers. [J.W. Sun et al., Appl. Phys. Lett. 100, 252101 (2012)].
Shockley-Frank stacking faults in 6H-SiC
Shockley-Frank stacking faults (SFs) identified in 6H-SiC by a
combination of low temperature photoluminescence and high
resolution transmission electron microscopy. In the faulted area,
stacking faults manifested as large photoluminescence emissions bands located in between the 6H-SiC signal (at ~ 2.99 eV)
and the 3C-SiC bulk-like one (at ~ 2.39 eV). Each of the stacking
fault related emission band had a four-fold structure coming
from the TA, LA, TO and LO phonon modes of 3C-SiC [J. W. Sun
et al., J. Appl. Phys. 111, 113527 (2012)].
Negative-U System of Carbon Vacancy in 4H-SiC.
Using electron paramagnetic resonance (EPR), energy levels of
the carbon vacancy (VC) in 4H-SiC and its negative-U properties
have been determined. Combining EPR and deep-level transient
spectroscopy, the two most common defects in as-grown 4HSiC–the Z1/2 lifetime-limiting defect and the EH7 deep defect–
have been identified to be related to the double acceptor (2-|0)
and single donor (0|+) levels of VC, respectively. [N.T. Son et al.,
Phys. Rev. Lett. 109, 187603 (2012)].
The influence of substrate morphology on thickness uniformity and
unintentional doping of epitaxial graphene on SiC
A major part of the research related to graphene on SiC prepared by high temperature sublimation has been focused on
understanding the effect of the graphene surface morphology
on its properties. Monolayer and bilayer graphene has been
investigated. Effect of environment conditions has been studied
as well. [J. Eriksson et al., Appl. Phys. Lett. 100, 241607 (2012); F.
Giannazzo et al., Phys. Rev. B 86, 234422 (2012)]
Nucleation control of cubic silicon carbide on 6H-substrates
It has been demonstrated that when using 6H-SiC substrates
3C-SiC nuclates on a homoepitaxial layer grown prior to the
cubic material. Ones nucleated 3C growth rate becomes higher
than that of the 6H-SiC. Supersaturation has been calculated
via thermal simulation in the growth cell and shown that the
supersaturation non uniformities resulted in 6H-SiC inclusions.
These findings were used to propose proper growth conditions
of high quality bulk-like cubic SiC. Another project was to develop new substrates for optimized epitaxial graphene – cubic SiC
[R. Vasiliauskas et al., Cryst. Growth and Design 12, 197 (2012)].

on a truncated area located at the apex of the hexagonal GaN
pyramid (Fig. 4). [A. Lundskog et al., Nanotechnology 23, 305708
(2012)].

migration at the defect area (green “C”). The area marked by blue “B” circle
show no change with after deposition and annealing.
Changes in structural and electronic properties of graphene grown on
6H-SiC(0001) induced by Na deposition
The effects of Na deposited on monolayer graphene on SiC(001)
were investigated. The experimental results show that Na prefers
to adsorb on the graphene layer after deposition at room temperature. A fully Na intercalation at the graphene-SiC interface
was obtained after heating at about 75 ºC. Interestingly, the two
bands show different locations of the Dirac point after heating
and both exhibit linear dispersion in the vicinity of the point and
not the hyperbolic dispersion observed for AB stacked bi-layer
graphene. [S. Watcharinyanon et al., J. Appl. Phys. 111, 083711
(2012)].
On the polarized emission from exciton complexes in
GaN quantum dots
The optical linear polarization properties of exciton complexes in
asymmetric Stranski-Krastanov grown GaN quantum dots have
been investigated experimentally and theoretically. It was demonstrated that the polarization angle and the polarization degree
can be conveniently employed to associate certain emission lines
in the recorded photoluminescence spectra to a specific dot (Fig.
5). The theory further predicts that the polarization degree can
provide information about the charge state of the dot. [ S.Amloy
et al., Appl. Phys. Lett. 100, 021901 (2012)].

peak intensities of the emission lines XX, X, A and B as a function of the polarization angle along with curve fittings. X and XX originates from the same
QD, while both A and B originate from different QDs.

Formation of nitride based pyramidal dots
InGaN quantum dots have been fabricated on top of hexagonal
GaN pyramids by selective area growth using hot-wall metal
organic chemical vapor deposition. To understand the growth
mechanism of these InGaN QDs, correlated scanning transmission microscopy (STEM) and micro-photo-luminescence (µPL)
measurements were performed. It is found that the InGaN QDs

CVD growth of sp2-hybridized rhombohedral boron nitride.
(M. Chubarov, H. Pedersen, H. Högberg, A. Henry). The
epitaxial growth of sp2-hybridized rhombohedral boron nitride
(r-BN) using chemical vapour deposition has been investigated
using ammonia and triethyl boron as precursors and sapphire
as substrate. Hydrogen gas is necessary for the formation of
r-BN, whereas its formation is considerably damped when using argon as the carrier gas. The presence of Si atoms in the
process improves the crystalline quality of the growing film and
contributes to the growth of high quality epitaxial r-BN instead
of less ordered t-BN film. The incorporation efficiency is found
rather low with an accumulation on the surface. [Cryst. Growth

Detailed studies of Si intercalation/de-intercalation of graphene on
6H-SiC(0001)
The intercalation and de-intercalation mechanisms of Si deposited on monolayer graphene grown on SiC(0001) substrates
and after subsequent annealing steps were investigated. After
Si deposition on samples kept at room temperature, small Si
droplets were observed on the surface, but no intercalation can
be detected. Intercalation was revealed to occur at an elevated
temperature of about 800 °C. The Si was found to migrate to
the interface region via defects and domain boundaries. This
observation may provide an answer to the problem of controlling
homogeneous bi-/multilayer graphene growth on nearly perfect
monolayer graphene samples prepared on SiC(0001). [C. Xia et
al., Phys. Rev. B. 85, 045418 (2012)].

Elastic constants, composition, and piezolectric polarization in
InxAl1−xN
We have reported for the first time a detailed study on the lattice
parameters and stiffness constants of InxAl1−xN and discuss
in detail their deviations from Vegard’s rule, and effects on the
determination of the alloy. We also reported for the first time the
piezoelectric polarization behavior for InxAl1−xN with arbitrary
surface orientations pseudomorphycally grown on GaN and discuss the implications of the deviations from Vegard’s rule in the
lattice parameters and stiffness constants. The detailed discussions provide guidance to experimentalists on the appropriate
approaches to estimate composition and piezoelectric polarization for InxAl1−xN with different compositions, surface
orientations and degrees of strain. [M.-Y. Xie et al., Phys. Rev. B

performance of emerging AlN semiconductor” presented at the
XI Brasilian MRS, 23-27 Sept 2012]; (ii) interplay between growth
kinetics and thermodynamics to alter the conditions for point
defects incorporation [“Shallow donor and DX behaviors of Si in
Si-doped AlxGa1-xN (x > 0.70)”, paper nominated for IWN2012
Best Paper Award, International Workshop on Nitride Semiconductors 2012, Sapporo, Japan]; and (iii) AlN scalability [E.F. de
Almeida Junior et al., “Defects in hexagonal-AlN sheets by firstprinciples calculations”, [Eur. Phys. J. B 85, 48 (2012)]
Manga & EuSiC
Manga and EuSiC are two large-scale joint multinational initiatives of leading system houses and research laboratories in
Europe aiming at the development of independent and state-ofthe-art capability in GaN HEMT technology. Manga program is
a continuation of the KORRIGAN program with dedication to
build up a European supply chain of GaN HEMT technology.
LiUs participation within Manga is material development with
focus on interface properties between the SiC substrate and the
nitride epilayer and to improve the thermal dissipation. The goal
of EuSiC is to develop high quality European GaN-Wafer on SiC
substrates for space applications and to create an independent
European supply chain for space technology. Linköping University will grow HEMT structures on 3” wafers, which then will
be processed at the European process house, United Monolithic

made of the wide band gap semiconductors: GaN/AlN/InN
based quantum wires and dots.

Within the NANO-N consortium, financed by SSF, nitride based
quantum dots for optoelectronic applications are investigated.
The focus is towards fabrication and optimization of photon
emitting GaN/InGaN based quantum dots structures.
Within the Nano-N project, the development of deterministic
InGaN quantum dots (QDs) at the apices of GaN pyramids has
been focused. For practical QDs device applications, the QDs
must be positioned in a controllable manner in order to facilitate
efficient device processing. Most InGaN quantum dots reported
up to date, consist of QDs randomly distributed across a planar
sample area. This is a consequence of the Stranski–Krastanov
(SK) growth method, enabling self-assembly of the QDs. The
growth of InGaN QDs at the apex of a hexagonal GaN pyramid is
an elegant site controlled approach, which we have developed in
our hot-wall MOCVD reactor. The reproducibility and performance of these site controlled pyramidal dots have now attained
such a maturity that we can proceed with more detailed investigations of the optical and structural properties of the InGaN dots.
Nitride based pyramidal quantum dots
The GaN pyramids were produced by growing GaN on photolithographically-patterned substrates by means of selective area
growth. On top of these pyramids, a thin InGaN/GaN quantum
well and a GaN capping layer were grown. The growth process
was tuned till the films had state of the art quality structural
quality and comparable with the best InGaN materials presented
in the literature. An InGaN QD is formed at the apex of the GaN
pyramid due to the pronounced (tensile) strain at the apex. Tunable QD emission energy by varying the growth temperature of
the InGaN layers is also demonstrated.
Ternary nitride based nano rods
Ternary Al1-xInxN nanorods have been produced by ultra-highvacuum magnetron sputter epitaxy (MSE) by cosputtering highpurity Al and In targets under ultra-high-pure nitrogen atmosphere. The crystal structure of the nanorods is wurtzite without
mixing zinc-blende phase. Although the Al1-xInxN nanorods
have hexagonal cross-sections in geometry, the nanorods have
phase separation and forms core-shell structure with higher In
content in the core. Furthermore, self-assembled superlattices
(SLs) in the rods were observed. Optical characterization of nitride quantum dots
The formation of individual InGaN QDs grown on GaN micropyramid arrays is evidenced by observing single, sharp, excitonic
emission lines of excitonic origin from various pyramids in the
optical characterization by means of micro-photoluminescence
(μ-PL). These μ-PL spectra demonstrate that our process gives a
better controllability on the dimension and/or the composition
of the dots compared to e.g. conventional SK dots.

symposium on “Alternative approaches of SiC and related wide

which was accepted at the E-MRS 2013 Spring Meeting. The
collaboration initiated a previously unexplored research area of
cubic silicon carbide for a highly efficient solar cell by impurity

Electron microscopy on nitride pyramidal quantum dots
The superior spatial resolution and analytical capacity of the electron microscope has been employed to analytically investigate
nitride quantum structures with a spatial resolution below 1 nm.
Currently, we have investigated the pyramidal structures, in particular the truncated area of the pyramid on which is crucial for
the formation of the quantum dots. By means of the world class
electron microscopy in Linköping, these understandings will be
employed to investigate in detail the localization, segregation
and diffusion of quantum structures throughout the remaining
period.

Industrial Research Project with LG Innotek
During 2010, a large collaborative effort between Semiconducting Materials and LG Innotek was started. The project, which is
sponsored by LG Innotek and the State of South Korea, strives to
develop uniform epitaxial layers for power device material on 4”
wafers using the chlorinated epitaxial process that has been studied here for several years. For this purpose LG Innotek placed a
new commercial CVD reactor at LiU that can effortlessly handle
4” wafers. The full project is anticipated to last for 9 years split
into three stages. In total the research funding to the Semiconducting Materials group is worth 20 MSEK not counting the
CVD reactor. Researchers from LG Innotek are here at LiU to
learn the fundamentals of CVD and to study the chlorinated
chemistry
NORLED – Northern Light Emitting Diode Initiative (M Syväjärvi,
R Yakimova).
NORLED (www.ifm.liu.se/norled) is a project funded by Nordic
Energy Research. It explores a new research area of light emission from silicon carbide. The light properties have the potential
to lead to a white LED for general lighting, as it is able to deliver
a pure white light or a warm white LED. Besides it has the advantage that it does not use a phosphor and rare earth metals. In
2012, the research findings lead several discoveries about optimi-
The research within the division of Surface and Semiconductor
Physics includes the following fields. Firstly, basic studies are
made of the electronic and atomic structure of semiconductor surfaces, either clean or with well-characterized overlayers.
Foreign atoms on a surface may result in a large variation of
ordered atomic structures, i.e., surface reconstructions. Physical
properties like metallic or semiconducting surface conductance
may depend on what reconstruction is formed. Various physical
properties are studied using a range of different techniques. The
most important one is photoelectron spectroscopy from which
one can obtain a complete determination of the surface electronic structure. These studies are performed at the synchrotron
radiation facility, MAX-lab in Lund, Sweden. Another important
technique that we use is scanning tunneling microscopy (STM)
that provides information about the atomic structure of the different surfaces. A variable temperature STM (Omicron) in our
lab at IFM is the major instrument used for these studies. Over
the period of several years we have also built up an experience
in theoretical studies of various systems. We find the capability
to do both experimental and theoretical studies quite important.
It gives us the advantage that we can approach a problem from
both the experimental and theoretical side to obtain a complete
picture of the electronic and atomic structure.
Within this field, the division was supported by the Swedish
Research Council (VR) as Roger Uhrberg has one research grant
for studies of the atomic and electronic structure of semiconductor surfaces.
Secondly, there are studies, development and application of
silicon-based molecular beam epitaxy (MBE), which is a crystal
growth technique to produce advanced semiconductor structures
63
material physics
for fundamental physics and device studies. We have also built
up competence and process capability for the development of
some device modules like SiGe-heterojunction bipolar transistors (HBT) for applications in optoelectronics and rf technologies.
Within this field, Wei-Xin Ni has recently gained one research
grant from VR for studies of the silicon epitaxy on silicide
templates for applications in extremely high frequency HBT
technologies.
We are extensive users of the synchrotron radiation facility
MAX-lab in Lund and over the years we have built up experimental equipment at two different beam lines. One of us, Uhrberg,
is working actively with the angle-resolved photoelectron spectroscopy (ARPES) beam line, which is one of the first seven to be
built at MAX IV. The beam line, which will be located at the 1.5
GeV ring, has received a funding of 70.2 MSEK.
Courses
The division has during the year been responsible for the following undergraduate courses for students within the Engineering
Programs and the International Masters Program on Material
Science: TFYA38 Optoelectronics (Ni), TFYA25 Physics of Condensed Matter, part II (Uhrberg). The Ph. D. course Solid State
Physics I was given by Uhrberg.
Highlights
1) The structural and electronic properties of the two-dimensional Sn/Ag/Ge(111)3x3 surface alloy has been studied. This is a
rare example of a system that forms a well ordered, one atomic
layer thick, alloy. Experimental techniques like low energy
electron diffraction (LEED), scanning tunneling microscopy (STM), and angle resolved photoelectron spectroscopy
(ARPES) are complementary, and they combined provide both
electronic and atomic structure information. Figures 1a and 1b
present filled and empty state STM images of the same area of
the 3x3 structure, respectively. The STM images are representations of the density of states within the energy range set by the
tunneling voltage. The parallelograms drawn in Figs. 1a and
1b outline the unit cell that is nine times as large as that of the
substrate. The filled state image is dominated by one protrusion while the empty state image show two protrusions per
unit cell. Each protrusion in the filled state images corresponds
to several Sn and/or Ag atoms. The electronic structure
that gives rise to the STM images can be studied in detail by
ARPES. Fig. 1c shows the intriguing Fermi surface consisting
of overlapping triangles at every K-point and a complex shape
at G. The electronic bands that disperse across the Fermi level
have a free electron like shape, with a high electron velocity.
These steep bands, with almost linear dispersion, are clearly
seen in Figs. 1d and 1e.

Ge(111)3x3 surface alloy, respectively. c) Fermi surface of the surface alloy. d)
and e) Surface band dispersions along the symmetry direction in b). The Fermi
surface is formed by the uppermost, steeply dispersing, bands.
2) Following the earlier success in fabricating RF- and photonictransistors using Si/SiGe-heterojunction structures made by
molecular beam epitaxy (MBE) with improved performance,
the group continues its effort in making Si-based epitaxial
layer structures for advanced device applications. A growth
technique has been recently developed, which enables the
epitaxial growth of Si layers on some silicide templates.
Si-on-silicides or vice versa are highly interested for many device
applications, in particular, SiGe-heterojunction bipolar transistors (HBTs) to operate at extremely high frequencies, e.g., with
a fmax value beyond the 0.5 THz forecast of the International
Technology Roadmap for Semiconductors (ITRS). One obstacle
that blocks research was occurrence of the Si 3D growth due
to a result of strong local distortion and a large bond-energy
difference between Si and metal atoms, although the crystalline
structures are similar with a very small lattice mismatch between
Si and some silicides, e.g., CoSi2 (a0=5.364 Å compared to
a0=5.430 Å for Si) and NiSi2 (a0=5.406 Å).
In our approach, the growth experiments were carried out on
the patterned Si substrate, supplied by Uppsala University, with
6-nm thick Co1-xNixSi2 strips of 1-10 μm in width. With an elaborate in situ surface cleaning process using a Si beam, and the
substrate temperature modulation during growth to trade off the
nucleation rate and dislocation propagation, defect-free Si layers
with a thickness below 10 nm have been successfully grown on
Co1-xNixSi2 strips. The interface between Si and silicate was very
flat and coherent, as evidenced by high-resolution transmission
electron microscopy.
The group has also recently initiated some research activities
aiming at developing the techniques that can produce an oxide
layer on silicon-carbide (SiC) with improved interface properties and a high dielectric strength. By investigating the detailed
chemical processes involved during the oxidation of SiC, we pro-

Aims and Vision
We conduct application-inspired basic research on thin films
to fundamentally understand the atomistic nature of materials
properties and behavior and learn how to make materials perform better through new methods of synthesis and processing. Emphasis is put on the relationships between growth from the
vapor phase, microstructure and properties of advanced functional materials. We thus extend the frontiers of materials and
nanosciences to expand the scientific foundations for the development of materials. Our research concerns unsurpassed design
of new multi-functional materials for engineering, electronics,
and the life sciences. Results are explored in collaboration with
industry and the properties of structures unique to thin films
form the basis for new and improved materials and processes.
We further seek novel phases and structures, as well as discovering materials phenomena.
Research Program
Our research concerns the materials science and nanotechnology of thin films. It is aimed at increasing the understanding of
vapor phase deposition, ion-surface interactions, and reactions in
advanced materials. Specifically, we probe into the nature of epilayers, textured thin films, and nanoscale materials. Model systems include transition metal nitrides, wide-band gap nitrides,
multifunctional ceramics (MAX phases; e.g., Ti3SiC2, Ti2AlN),
nanocomposites, superlattices, fullerene-like compounds, low
dimensional phases, cluster-assembled materials, and multilayers. The core techniques operated and developed by the Thin

Theory and Modeling
The program ‘Theory and Modeling (T&M)’ at the Department
of Physics, Chemistry and Biology (IFM) includes Theoretical
Physics, Computational Physics, Theoretical Biology, and Bioinformatics. The field of theory and modeling is presently in
a very expansive phase. The reason is the profound and rapid
development of computers, efficient algorithms, software, and
immense databases that we experience today. It offers new and
rich opportunities to solve in realistic ways many important
problems. Moreover most challenging problems for modern science, the discovery of new and clean energy sources,
understanding the structure of the Earth’s core, understanding
mechanisms of protein function, solving the protein folding
problem, and understanding the ecological consequences of
global climate change require truly interdisciplinary efforts.
Only a few years ago the complexity associated with shape,
intricate boundary conditions, different length and time scales,
immense amount of data, etc., simply made it prohibitive to
tackle problems of this kind. Today we consider them with
great success.
The general field of theory and modeling is also becoming
increasingly important because it may supplement expensive
and/or time consuming experiments and product developments with realistic simulations based on mathematical
models, rapid access to large databases, etc. It may also replace
hazardous, dangerous and/or very expensive experiments and
even substitute inaccessible experiments. It is also important to
point out that though the disciplines at T&M represent broad
scientific fields, from physics to biology, they all rely on a common core of mathematical modeling, mathematical/numerical methods, and simulations. The computational problems
usually deal with complex systems that require a wide range of
scientific knowledge: problem formulation, mathematical modelling, numerical analysis, programming for parallel execution,
hardware solutions, tools for analysis and visualization etc.
There are about fifty persons actively engaged in T&M. To
organize common activities within T&M there is a steering
committee, which includes Igor Abrikosov (theoretical physics
and head of theory and modeling), Bo Ebenman (theoretical
biology), Bengt Persson (bioinformatics), and Sven Stafström
(computational physics). Lejla Kronbäck, Anna Sundin, AnnaKarin Stål and Malin Wahlberg acted as administrative assistants. Members of T&M carry out innovative research. In 2012
we published 82 papers in international journals with referee
system. Our papers are well cited. We gave large number of
invited talks at international conferences. Members of T&M are
active in undergraduate and graduate teaching.
IFM is a motivating place for conducting theoretical programs, because it offers close contact with experimental activities and educational programs in engineering and science.
Another important aspect is the access to the computational
facilities and expertise at the National Supercomputer Center
(NSC). In particular, our groups and NSC are actively involved
in Swedish e-Science Research Centre (SeRC). We are actively
participating in the Interdisciplinary Materials Science Laboratory for Advanced Functional Materials (AFM). Both, SeRC
and AFM are supported by the Swedish Government. We are
involved in Linnaeus Strong Research Environment supported
by the Swedish Research Council, in Strategic Research Centres “Multifilms”, “Center of Organic Electronics (COE)”, and
FUNCASE supported by the Swedish Foundation for Strategic Research. Also, we are part of FORMAS Strong Research
Environment “Centre of Excellence for Farm Animal Welfare
Research”, as well as projects “Isotopic Control for Ultimate
Material Properties” and “Nanoparticles by Pulsed Plasma” supported by Knut and Alice Wallenbergs Foundation.
T&M represents a broad and interdisciplinary research
program. To find out more about each other research, we
organize annual group meetings, “Theory and Modeling
Day”. In 2012 we met on December 19 (see photo) and
discussed climate modeling. The conference program included a visit and presentations at SMHI (Norrköping) followed by presentations of T&M alumni, working at SMHI,
Christian Asker, Mattias Jakobsson, and Nina Håkansson, as well as a presentation from NSC by Johan Raber.

Characterisation of protein families
We develop methods and strategies for protein family characterisation, including hidden Markov-model-based classification of the superfamilies of SDRs and MDRs (short-chain and

Membrane protein structure prediction
We develop methods that can predict the structure of fairly
complex membrane protein topologies from sequence information alone. We have also extended these methods to utilize
limited structural information such chemical cross-crosslinks,
metal-bridges or predicted interactions to improve these predictions further. Membrane proteins are a class of proteins with a
severe gap between its occurrence in the genomes (30%) and
the fraction of known protein structure (<1%). At the same time
they are highly interesting since they are the gates to the cell
and are involved in a wide variety of functions such as signal
transduction, transport and cell-cell recognition. They are also
the main targets for drugs on the market today. Structural
knowledge for this important class of proteins is crucial to
understand function and to be able to model the effect at the
molecular level of small molecules and drugs.

membrane insertion. In a recent collaborative effort with experimental groups
in Spain, we used computational modelling to explain mutational data (cf.
Figure 1).
Prediction of protein domain interaction
We are developing methods that utilize the massive amount of
growing sequence data available to find subtle compensatory
single point mutations in protein domain to predict interaction

Protein model quality assessment
With the rapid increase in computer power it is now easy to
generate thousands of alternative models for a given protein
sequence, using different methods and alternative alignments.
This has transformed the field of protein structure prediction
from predicting one single structure to selecting one structure
for a large set of alternatives. We have pioneered in this field
with both our consensus-based methods (http://pcons.net)
and with our machine learning based model quality assessment programs, ProQ and ProQM. Our latest version of ProQ,
ProQ2 was ranked no 1 in its class at CASP10, the biennial
community-wide assessment of these methods.
Structural calculations and predictions
We use molecular modelling techniques to study molecular
interactions and sequence variations in relation to structural
changes. This methodology is applied to predict the effects of
mutations in cancer-related proteins.
Facilitating analysis of massive amounts of sequencing data
Bioinformatics methods and strategies have been developed for
usage in large-scale metagenomics projects. These include an
automated highly efficient BLAST search and result analysis
pipeline, a novel alignment algorithm to produce more robust
and accurate results with 454 data, and a new alignment tool
HAXAT, allowing for on-the-fly correction of sequence read
errors. The novel techniques have been used to analyse naso-

General
In their work to describe electronic structure and electronic
motions in molecular materials, the Computational Physics
group employs a wide variety of methods including molecular
mechanics and molecular dynamics for studies of structures
and morphology, first principles electronic structure theory,
response theory (for spectroscopic applications), DFT and
TD-DFT, QM/MM methods, finite size scaling for studies of
electron localization, the Landauer formalism, electron lattice
dynamics and Monte Carlo methods for studies of charge
transport. Most of the systems that we are studying are based
on carbon but also silicon based systems, III-nitrides, etc are
being modeled. The research cuts across a range of disciplines
(molecular and supramolecular electronics, photonics, materials and polymer science, cluster-assembled compounds and
low-dimensional phases, device physics, photochemistry and
biochemistry) with many applications in the fields of nanotechnology, optoelectronics, and organic electronics.
The Computational Physics group gives a large number of
courses on graduate as well as under-graduate levels: Classical
Mechanics (undergraduate,MB), Quantum Mechanics (undergraduate, MB), Computational Quantum Chemistry (graduate, PN, ML, BD), Potential Energy Surfaces and Dynamics
(NGSSC school, graduate, ML). Two diploma students have
been working in the group during the year.
Patrick Norman was appointed director of the National Supercomputer Centre, NSC, at Linköping University.
The group organized the 2012 annual meeting of Svensk Teoretisk Kemi (STK), August 23-24, 2012.

We first demonstrated how two-dimensional sheets are
incorporated in the formalism for planar structures. Then we
derived the interaction in the geometry of two freestanding
graphene sheets and of one graphene sheet above a substrate.
Numerical results were produced for the fully retarded interaction at 0 K and at room temperature for undoped and doped
graphene. Additional results were given both for a gold substrate and for an ideal metal substrate. We found that for two
freestanding undopedgraphene sheets the retardation effects
are negligible. The same holds for an undoped graphene sheet
above a gold substrate. This behavior is very unusual and is the
result of the particular band structure of graphene. However,
for doped graphene sheets, two freestanding or onefreestanding above a gold substrate, the retardation effects are bound to
be important at large enough separations. However,at T = 300
K the retardation effects again go away.

Exact localized eigenstates for an extended Bose-Hubbard model with pair-correlated hopping [P. Jason and M. Johansson,
Phys. Rev. A. 85, 011603(R) (2012) (Rapid Communication)]
The increasing precision and tunability of ultracold atoms in
optical lattices has greatly increased the interest for quantum
lattice models, such as the Bose-Hubbard model. Ordinarily
only interactions between bosonic atoms located on the same
site are included, but extending the model with effects from
longer-range interactions such as pair-correlated hopping between nearest neighbours may lead to new physical effects.
We showed that this extended Bose-Hubbard model has exact
one-site “Quantum Lattice Compactons”, being eigenstates
with complete localization of all particles at one site. These
appear at parameter values where the one-particle tunneling is
exactly canceled by nonlocal pair correlations, and correspond
in the limit of infinite particle number to exact compact solutions (“discrete compactons”) of a classical lattice model. Classical compactons existing at other parameter values, as well
as exact multisite compactons, generically get delocalized by
quantum effects, but strong localization appears asymptotically
for increasing particle number. Compactons are interesting for
applications due to their tail-less nature, prohibiting mutual
interactions unless being in direct contact.

We analyze the occurrence of local magnetization and the effects of electron localization in different models of quantum
point contacts (QPCs) using spin-relaxed density functional
theory (DFT/LSDA) by means of numerical simulations. In the
case of soft confinement potentials the degree of localization
is weak and we therefore observe only traces of partial electron
localization in the middle of the QPC. In the pinch-off regime
there is, however, distinct accumulation at the QPC edges.
At the other end, strong confinement potential, low-electron
density in the leads and top or implant gates favor electron
localization. In such cases one may create a variety of electron
configurations from a single localized electron to more complex structures with multiple rows and Wigner lattices.

theory. As a consequence, the study of iron and iron-based
alloys has been a focus of experimental and computational
research over the past decades. While the structural properties
of iron and iron-nickel alloys at pressures below 100 GPa are
well established, their electronic and magnetic properties are
still debated. Our state-of–the-art ab initio calculations of the
Fermi surface of Fe within the dynamical mean-field theory
(DMFT) reveal a change of its topology, the so-called electronic topological transition (ETT) at pressures of about 30-40
GPa (see the figure). The ETT manifests itself through anomalous behavior of the Debye sound velocity, c/a lattice parameter
ratio and Mössbauer center shift observed by our experimental
colleagues. The ETT is absent in one-electron calculations (see
the figure) and represents a clear evidence of the importance of
correlation effects in Fe at high pressure.

Exploring ZnO Nanostructures Embedded in Polymers for
Enhanced Performance in Light Emission and Photovoltaic
Applications
Fengling Zhang IFM, LiU
We prepared varied ZnO nanostructures. The light emission
of the nanorods was studied by μ-PL in the temperature range
of 4 – 300 K. The low temperature PL spectrum of high quality
ZnO nanorods is solely dominated by NBE emission, which
consists of several closely located peaks, attributed to the donor
bound exciton emission (D0X)(Fig.1a). The ZnO nanoarray as elecrtron acceptor was integrated in Hybrid solar cells
(HSCs) with polymer Poly[2-methoxy-5-(2′-ethyl-hexyloxy)1,4-phenylene vinylene] (MEH-PPV) as electron donor. The
current density (J)-voltage (V) curves are shown in Fig.1b. The
performance of the HSCs is mainly limited by large dimensions of ZnO nanostructures (diameter 100 nm and length 500
nm), which can be improved with reduced the dimensions of
nanostructures by one order of magnitude.

Objective
Our objective is in doing basic research to fundamentally understand the atomistic nature of materials synthesis, structure, and
properties. We can thus extend the frontiers of materials and
nanosciences to expand the scientific foundations for the development of materials that improve, e.g., the efficiency, environmental acceptability and safety in energy generation, conversion,
transmission and use.
The core activity of LiLi-NFM is within the largest and most
rapidly developing area of physics research worldwide. In fact,
the understanding of materials is the fundamental driving force
in natural science and basic engineering research. We focus
on studies on the nature of epilayers, thin films, and nanoscale
materials. Here, we are in the forefront regarding materials synthesis including wide-band gap materials (SiC, BN, AlN, GaN,
ZnO), graphene, nanocomposites, superlattices, fullerene-like
compounds, and organic molecular materials.
80
Our research concerns unsurpassed knowledge-based design of
new functional materials for electronics, engineering, and the
life sciences. We design material structures and explore outstanding phenomena. We also seek to discover novel phases.
Graphene Flagship
Linköping University is taking part in the Graphene Flagship
ramp-up stage, which is funded by EC within the FP7. The
decision of funding is opening for the graphene researchers
new horizons to bring this amazing material to revolutionary
solutions in high speed electronics, medical diagnostics, space
research, etc.
Researchers at IFM have the knowhow to produce one of the
best graphene on silicon carbide worldwide. In November 2011
the first European company on epitaxial graphene (Graphensic
AB) was founded as a spin off from LiU.
One of the goals of the Graphene Flagship is to bridge
research and commercialization by creating new and improved
graphene products to be implemented in advanced applications,
which will bring added value to the society.
The existence of a highly ordered, two-dimensional, Sn/Ag
alloy on Si (111) is reported in this study. We present detailed
atomic and electronic structures of the one atomic layer thick
alloy, exhibiting a 2x2 periodicity. The electronic structure is metallic due to a free-electron-like surface band dispersing across
the Fermi level. By electron doping, the electronic structure can
be converted into a semiconducting state. A rotated Sn trimer
constitutes the key structural element that could be identified by
a detailed analysis of constant energy contours derived from the
free-electron-like band.
Strategy
It is our strategy for excellence to develop and integrate theory,
simulations, and experiment. The philosophy for operating LiLiNFM contains the following elements:
• Natural science and basic engineering research
• Strategic recruitments and tenure-track plans
• Intra-disciplinary excellence
• Inter- and multi-disciplinary modus operandi
• Strong national & international collaboration
• State-of-the-art laboratories
• Leading computational capacity
• Synergy and added value from collaboration

structures [D. Dagnelund, Q. J. Ren, I. A. Buyanova, A. Murayama, and W. M.
Chen, Appl. Phys. Lett. 101, 052405 (2012).]
Spin polarization of nonmagnetic CdSe quantum dots (QDs)
coupled to adjacent ZnMnSe diluted magnetic semiconductor
(DMS) is investigated by CW and time-resolved magneto-optical
spectroscopy under tunable laser excitation. Efficient enhancement in the degree of σ− circular polarization of photoluminescence from the CdSe QDs is observed under optical excitation at
the σ+-active exciton state of the DMS. The fact that the enhancement persists much longer than the exciton lifetime of the DMS
rules out a role of the DMS excitons. A possible explanation is
discussed in terms of antiferromagnetic coupling between the
excitons in QDs and aligned Mn ions in DMS.

in order to investigate the stability and the electronic structure
of graphene-gold interfaces. Two configurations were studied:
an Au cluster interacting with graphene and different polycyclic aromatic hydrocarbon (PAH) molecules, namely, C6H6
(benzene), C24H12 (coronene), and C54H18 (circumcoronene)
adsorbed on Au(111). Nonlocal interactions were accounted for
by using the semiempirical DFT-D2 method of Grimme. A
limited set of calculations were also performed by using the firstprinciples van der Waals density functional method (vdW-DF).
Adsorption distances around 3 Å and electronic charge transfer
values of about (3–13) × 10−3 e− per C atom were predicted for all
systems. No major changes resulting from the adsorption of the
Au cluster were detected in the graphene’s density of states. The
DFT-D2 results involving the adsorption of the PAH molecules
on Au show an estimated binding energy of 73 meV per C atom,
as well as an electronic charge loss of 0.10 × 10−2 e− per C atom,
for an extended graphene sheet adsorbed on a Au surface. The
modeling of the adsorption of C6H6 molecule on a Au surface
suggests that the vdW-DF method provides more accurate results
for the binding energies of such systems, in comparison to pure
DFT calculations, which do not take the nonlocal interactions
into account, as well as to simulations employing the DFT-D2
method.

Size-Controlled Growth of Nanoparticles in a Highly Ionized
Pulsed Plasma [I. Pilch, D. Söderström, N. Brenning, and U.
Helmersson, Appl. Phys. Lett., 102, 033108 (2013)].
Nanoparticles in a size range of 10 to 40 nm were synthesized
using a high power pulsed hollow cathode. It was shown that
the size of the nanoparticles could be controlled by the pulse
parameters, i.e., frequency, peak current and pulse width. By
applying a high power pulse to a hollow cathode, a high degree
of ionization of the sputtered source material is achieved. The
growth process of nanoparticles in a pulsed, highly ionized
plasma is discussed, and underlying mechanisms for controlling
the growth process are proposed.

Effect of point defects on the electronic density of states of ScN
studied by first-principles calculations and implications for thermoelectric properties [S. Kerdsongpanya, B. Alling, P. Eklund,
Phys. Rev. B 86, 195140 (2012)].
We have discovered an anomalously high thermoelectric power
factor in epitaxial ScN thin films, suggesting ScN-based materials as candidates for thermoelectric application. Our theoretical studies demonstrated that this is due to the defect states
introducing sharp features in the electronic density of states,
which would yield a large enhancement in Seebeck coefficient
without reduction in electrical conductivity. Sc and N vacancies
produce an asymmetric sharp feature in DOS of ScN. The other
defects will move the position of the Fermi level (EF) depending
on whether they are donors or acceptors, for example O, F, and
Zr act as donors and C, Be, and Mg act as acceptor. Our results indicate a promising pathway to obtain high thermoelectric figure of merit in ScN-based materials by stoichiometry tuning and
reduction of lattice thermal conductivity.

Charge Redistribution Mechanisms of Ceria Reduction [O. Hellman, N. V. Skorodumova, and S. I. Simak, Phys. Rev. Lett. 108,
135504 (2012)].
Ceria is a core material of many modern environmentally
friendly technologies, which rely on its excellent redox properties. The efﬁciency of the oxygen vacancy creation and annihilation in ceria can be controlled by external parameters, such as
oxygen pressure and temperature, and modiﬁed by appropriate
doping. Unfortunately, only concentrations of oxygen vacancies exceeding 1.5 at. % are accessible in standard first-principles
calculations due to prohibitive computational cost for very large
supercells. In the present work we have proposed a model to
approach the dilute limit in the framework of the first-principles
density functional theory. Our model allows one to reproduce the
characteristic experimentally observed behavior of composition
versus oxygen pressure dependency. We have shown that in the
dilute limit the charge redistribution is likely to be driven by a
mechanism different from the usual one involving electron localization on cerium atoms. It can involve charge localization on
light element impurities. In particular, natural impurities, like
carbon and nitrogen, are able to act as catalysts jump-starting the
process yielding the redox properties of ceria (see Figure 6). The origin of the anisotropic Seebeck coefficient (thermoelectric
effect) in nanolaminated crystals is traced to anisotropies in
element-specific electronic states by employing polarized angledependent x-ray spectroscopy. These results constitute experimental evidence explaining why the average Seebeck coefficient
of Ti3SiC2 in polycrystals is negligible over a wide temperature
range.

Surface morphology effects on the light-controlled wettability of
ZnO nanostructures
[V. Khranovskyy, T. Ekblad, R. Yakimova and L. Hultman, Applied Surface Science 258, 8146 (2012)].
The effect of surface morphology on the UV light-controlled
wettability of ZnO nanostructures has been revealed [1]. The
hydrophobicity state of the ZnO nanostructures is converted
to superhydrophilicity after UV irradiation during ~5 - 30 min
(Fig. 1), where smaller ZnO features on the surface yield a faster
hydrophobicity-hydrophilicity transition. This is explained by
the semiconductor nature of ZnO and its surface chemistry.
The fastest and most prominent wettability change is obtained
for ZnO nanosheaves: the contact angle changes from 124º to
5º after ~ 5 min. of irradiation. Such effect is explained to be
due to the small (~30 nm) needle tip diameter and their highly
developed surface area. The results encourage the application
of the ZnO nanostructures, particularly for the effective control
of micro or nano-fluid motion, and enabling patterning hydrophilicity/hydrophobicity with photolithography. The observed
features of ZnO can also be used for the design of microdevices,
where the nature of a surface plays a key role on the mediation
of protein adsorption or cell adhesion.

Negative-U System of Carbon Vacancy in 4H-SiC [N.T. Son, X.T.

Phys. Rev. Lett. 109, 187603 (2012)].
Using n-type 4H-SiC epilayers irradiated by low energy (250
keV) electrons we were able to obtain the electron paramagnetic
resonance (EPR) signals of the carbon vacancy (VC) without
interference from other defects and determine its energy levels
and negative-U properties. Combining EPR and deep-level
transient spectroscopy (DLTS), the two most common defects
in as-grown 4H-SiC–the Z1/2 lifetime-limiting defect and the
EH7 deep defect–have been identified to be related to the double
acceptor (2-|0) and single donor (0|+) levels of VC, respectively.
The results clarify the long-standing issue on the origin of the
lifetime limiting defect in bulk SiC.

The structural and electronic properties of an infinite h-AlN
sheet were addressed by DFT calculations together with the
implications for its network of selected defects, e.g., vacancies,
anti-sites as well as C and Si impurities. Defects such as nitrogen vacancies and Si impurities lead to a breaking of the planar
shape of the h-AlN sheet and in some cases to the formation of
new bonds. The defects significantly change the band structure
in the vicinity of the Fermi level in comparison to the band
structure of the perfect h-AlN, which can be used for deliberately
tailoring the electronic properties of individual h-AlN sheets.

GENERAL INFORMATION
The Linköping Biosensors and Bioelectronics Centre (LBB) was
set up in 2010, with the aim of bringing together the many competences, activities and resources at LiU that are already working
on, or can bring valuable contributions to, the development of
biosensors, biosensing, bioelectronic devices and relevant biomaterials and nanomaterials. The mission of the Centre is to improve the quality of life, health and the environment by the provision of distributed diagnostics and personalised analytical tools
and therapies. Its remit encompasses implantable, minimallyinvasive and non-invasive techniques that may be wearable, used
at the point of care or more widely distributed in the home or
environment. Disease management is focused on cancer, cardiac
diseases, infectious disease, diabetes and care of the elderly. The
Centre’s principal tools are high level research, advanced teaching and the organisation of specialist conferences and workshops. During 2012, the Centre consolidated with the appointment of a number of seniors, including three in association with
the Integrative Centre for Regenerative Medicine (IGEN). It also
played a leading role in the management of Linköping Initiative
in Life Sciences (LIST) and contributed to the strategic direction
of New Tools for Health (HNV). The Centre further reinforced
its role on the international stage in the rapidly expanding field
of biosensors by the creation of several key international collaborations, organisation of two international workshops and
several major conferences. Work at LBB today spans a full range
of core technologies including: bioimaging and drug delivery;
bio-inspired and bio-specific ligands; biointerfaces; biomaterials; biomolecular electronics; biosensors; chemical transducers;
pre-clinical trials; printing and microfabrication; micro-actuators;
nanomaterials and nanostructures; tissue scaffolds; smart materials and nanomaterials; therapeutics; and user interfaces and
electronic design.

The research activities at SIMARC cover several areas of various disciplines, including materials science, chemical physics,
chemistry, radiation physics and medical science. The materials studied include advanced semiconductor materials, organic
materials for dosimetry and biochemical materials.
The goal is, by electron paramagnetic resonance (EPR) and
optically detected magnetic resonance (ODMR), to identify
chemical nature and geometrical structure of defects, impurities and dopants that are important in semiconductor materials
and nanostructures. The activities in this area during 2012 were
focused on: (i) Ga(In)NAs and GaNP dilute nitrides; (ii) SiC;
and (iii) ZnO. EPR dosimetry
The aim is to improve EPR dosimetry (ionising radiation dose
measurements) to be a competitive dosimetric method for applications in radiation therapy. We worked with optimization of
measurement precision and accuracy in dose measurements
by development of new dosimeter read-out protocols and dosimeter calibration protocols. We were also searching for new
dosimeter materials with higher sensitivity and better tissue
equivalence with respect to attenuation and scattering of ionizing radiation. We are currently clinically evaluating a lithium
formate EPR dosimeter system for dosimetry in special measurements situations such as dosimetry in intensity modulated
radiation therapy (IMRT) and brachytherapy with electronic
sources i.e. a micro X-ray tube. Further the robust design and
high stability of the dosimeters were used for verification of the
whole radiotherapy chain.
Retrospective dosimetry by means of EPR spectroscopy
EPR spectroscopy measurements of chewing gums and
sweeteners sorbitol and xylitol have been performed in order to
optimize their use as retrospective dosimeters. We participated
in an international intercomparison on retrospective dosimetry
of Touch Glass in mobile telephones. Radical identification,
transitions, stability, dose response and light dependence have
been investigated. Retrospective dosimetry on finger nails has
been performed with a focus on the preparation procedures
to avoid mechanically induced signals. First attempts were
made on imaging of the dose distribution in tooth enamel by
imaging of simple geometries of enamel grains in paraffin and
carbonated hydroxyapatite.
Medical applications of EPR imaging (EPRI)
Research aiming to use EPRI for medical applications such as:
(i) imaging of radical distributions in atherosclerosis for a better understanding of the role of reactive oxygen species (ROS)
in atherosclerosis; (ii) imaging of radical distributions for
experimental verifications of calculated dose distributions in radiation therapy of cancer, e.g. narrow beam dose distributions
and interface dose distributions; (iii) imaging and spectroscopy
of spin-labelled amyloid proteins involved in degenerative
diseases.
is used to evaluate optical and defect properties of ZnO nanowires (NWs) grown by rapid thermal chemical vapor deposition.
By monitoring visible emissions, several grown-in defects are
revealed and attributed to Zn vacancies, shallow (but not effective mass) donor and exchange-coupled pairs of Zn vacancies
and Zn interstitials. It is also found that the intensity of the
donor-related ODMR signals is substantially lower in the NWs
compared with that in bulk ZnO, indicating that formation of
native donors is suppressed in NWs, which is beneficial for
achieving p-type conductivity. [J.E. Stehr et al, Nanotechnology
24, 015701 (2013)]
EPR and theoretical studies of Nb in 4H- and 6H-SiC
A Nb-related defect in unintentionally Nb-doped 4H- and 6HSiC is studied by EPR. A strong and anisotropic hyperfine (hf)
interaction with two equivalent Si atoms and a much weaker
hf interaction with the third Si neighbor are observed, showing considerable spin density on three Si neighbors of the C
vacancy. Comparing the hf data obtained by EPR and by hf
calculations provides further support for the identification of
the defect as the neutral Nb-vacancy complex, NbSiVC0. The
observation of only one Nb-related EPR spectrum in 4H- and
6H-SiC is in line with the result from previous calculations
predicting that the h-h configuration of NbSiVC0 is more stable than others. [N.T. Son et al., J. Appl. Phys. 112, 083711 (2012)]
Fe(III) distribution varies substantially within and between atherosclerotic plaques
Atherosclerotic plaques that are unstable may rupture and
the resulting thrombosis may cause subsequent catastrophic
events such as a stroke or a myocardial infarction depending
on the position of the atherosclerotic plaque. This work aims to
study if the vulnerability for rupture of carotid atherosclerotic
plaques is better correlated to intra-plaque iron distribution
and therefore to the localization of oxidative stress, rather than
to a high mean iron concentration in the plaque. We found
large intra-plaque Fe(III) variations in addition to the observation that plaques from patients with neurological symptoms
had a higher Fe(III) concentration as compared to asymptomatic plaques as well as signs of cap rupture and increased cap
macrophage activity. [Gustafsson et al., Magnetic resonance in
medicine, In press].
