Foreword
Welcome to Traunkirchen, Austria and the 10th International Workshop on Epitaxial Semiconductors on Patterned Substrates and Novel Index Surfaces !
ESPS-NIS focuses on recent developments in epitaxial growth of semiconductor nanostructures on non-planar patterned, vicinal or high-indexed surfaces. Prepatterning and novel index
surfaces are highly interesting and technologically important since they display many intriguing properties that may be exploited to obtain new fundamental insights in the mechanisms
of self-assembly and self-organization and enable a variety of interesting scientific and
industrial applications. These features range from engineering of nucleation sites for nanostructure growth to novel electronic properties for integration in photonic devices.
ESPS-NIS 2014 brings together about 60 researchers and scientist from all over the world
working in the field of growth, modeling, characterization and device applications, with the
previous workshops held in 2012 in Eindhoven, 2010 in Como and 2008 in Marseille. The
workshop spans three days from July 21st to 23rd, 2014 and features 1 plenary and 19 invited
speakers and 23 contributed presentations who will provide an comprehensive overview of
the current and future research directions in the field. The aim is to provide a forum for
intensive discussion and a high level of interaction in an informal environment.
The principal topics include:
● Self-assembly and site-control of nanowires and quantum dots
● Advanced nanopattering and growth on patterned substrates
● Novel materials including semiconductors, topological insulators,
graphene and layered materials
● Novel nanomorphlogies on vicinal and high-indexed surfaces
● In situ and in vivo growth studies
● Fundamental mechanisms and modelling of growth
● Structural, electronic, optical and transport properties of nanostructures
● Photonic structures
● Nanodevice fabrication and applications
As social events, there will be a welcome reception, a boat trip on the Traunsee lake with the
conference Banquet and a visit to Gmunden, as well as an optional full day excursion to Bad
Ischl and the Schafberg mountain after the scientific program.
We hope you will enjoy the conference with its exciting scientific program, social events and
pleasant surroundings of one of the most beautiful spots in the Austrian Alps.
