Tasks in the project:

  • Growth of In-free planar III-V layers with reduced Ga content on Si(100)
  • Growth of In-free QW structures with reduced Ga content on Si(100)
  • Growth of GaInP on Ge(100) with reduced Ga and In content
  • Photoluminescence measurements
  • Metal catalyst deposition on planar structures using photoelectrochemistry
 

Methods:

  • Metal-organic vapor phase epitaxy,
  • Reflection anisotropy spectroscopy,
  • Electron channeling contrast imaging,
  • Atomic force microscopy,
  • X-ray diffractometry,
  • X-ray photoelectron spectroscopy
