Materials research for group IV semiconductors: growth, characterization and technological developments III

Group IV semiconductors lie at the heart of many electronic and photovoltaic devices. Issues associated with bulk silicon continue to be important, but substantial fundamental challenges also exist for other group IV bulk materials and associated alloys, nanostructures, nanocomposites, thin/thick films and heterostructures. Advances in device performance are underpinned by new defect engineering procedures, development of novel growth techniques, and improvements in advanced diagnostic tools. Point and extended defects remain at the center of interest, as are surfaces, and in some cases their engineering represents an option for new functionalities.

In this edition of the Symposium, the organizers intend to hold a specific session dedicated to extended defects in cubic silicon carbide, so abstracts in this area are particularly welcome.

This symposium will include, but will not be exclusively limited to, the following topics:

Crystal growth of group IV semiconductors:

  • Modeling of defect generation and modeling of crystal growth
  • Crystal growth for solar applications
  • Growth of group IV alloy crystals
  • Wafering technologies and defect evolution in wafering processes
  • Large diameter crystal growth with emphasis on 450mm diameter wafers
  • Low quality polycrystalline silicon refinement, including control of dopants

Nanostructures of/ on group IV semiconductors:

  • Layer deposition for electronic and photovoltaic applications
  • Nanocrystalline materials
  • Quantum wires, vertical membranes for FinFETs, and quantum dots
