Summary

This course offers an insight into the science of epitaxial growth, a chapter of surface science requiring basic understanding of thermodynamics, crystallography, electronic and optical properties of semiconductors.

Content

Metalorganic Vapour Phase Epitaxy (MOVPE) is one of the main fabrication techniques of a large variety of widely studied semiconductor materials of key relevance for modern optoelectronic devices, for which this course illustrates the challenges, methods and achievements.

4)    Surfaces & growth modes

  • a) Surface characterization
  • b) Vicinal surfaces
  • c) Surface dynamics
  • d) Surface segregation
  • e) Surfactant mediated epitaxy

5)    Masked selective area epitaxy

  • a) Facet growth behavior
  • b) Alloy content modulation
  • c) Epitaxial lateral overgrowth
  • d) Template assisted selective area epitaxy

6)    Non-planar selective area epitaxy
