The 8th ESPS-NIS workshop will continue the success of the '94, '96, '98, '01, ‘03,'06, and '08 meetings, which were held in Italy, France, Spain, France, Germany, UK and France, respectively, by addressing the latest advances of growth, characterization and physics of epitaxial semiconductors on patterned substrates and on substrates with surface orientations not commonly used in semiconductor epitaxy.
This workshop focussed on recent experimental and theoretical progress in the growth, positioning, and properties of semiconductor nanostructures and on the fabrication and characteristics of new devices using semiconducting nanostructures grown on high index and nanostructured substrates. The objective was to share the established and complementary expertise of the different researchers in fundamental surface science, growth, modelling and electron transport physics of nanostructures, design of novel nanoelectronic devices.
The 7th ESPS-NIS primarily focussed on the following topics, of strong interest in fields of semiconductor nanostructures, high index surfaces and nanostructured substrates
- Epitaxial semiconductor nanostructures
- High index surfaces
- Electronic, magnetic, optical and transport properties
- Self-assembling techniques
- Pattern formation and characterization
- Quantum dots, quantum wires and their properties
- Techniques of nanofabrication and nanopatterning
- Atomic structure and morphology, surface and interface phenomena
- Novel device applications: nanodevice fabrication technology, characterization, properties and modelling
- Other applications in medicine, environment, etc.
- Novel properties of high index surfaces: electronic structure and modelling
The workshop covered three essential fields of current semiconductor research:
- The combination of epitaxial semiconductor growth and patterned substrates, which has gained tremendous attention in recent years since it is the most promising approach to accurately position, functionalise and eventually integrate self-assembled nanostructures on a single chip.
- Growth, characterisation and physical properties of self-assembled quantum dots, which are known to exhibit novel index surfaces.
- Substrates with orientations other than the commonly used (100), which are essential for tailoring electronic, optical and piezoelectric properties of semiconductors. Furthermore, these surfaces can act as templates to realize novel nano-objects.
Communications in relation to the following topics were accepted:
- Epitaxial growth of semiconductor heterostructures
- on high index surfaces
- on patterned or pseudo substrates
- containing self assembled quantum wires and dots
- Modelling or experimental studies on
- growth mechanisms
- spontaneous ordering and composition modulation
- strain relaxation
- doping incorporation and modulation
- magnetic properties
- piezoelectric effects
- Devices exploiting these novel properties
