Abstract:

Theories of the mechanical, vibrational, and electronic properties of III-V semiconductors have been developed and applied to 1 understanding the physics underlying the II-VI doping problem and suggesting band-gap engineering schemes for circumventing the problem 2 making predictions of how the character of deep and shallow impurities can be different in superlattices from in bulk materials 3 understanding how surfaces of zincblende and wurtzite semiconductors relax, and how this relaxation depends on the ionicity of the semiconductor 4 obtaining better insight into the properties of semiconducting alloys, both electronically and vibrationally, with attention paid to how ordering phenomena in these alloys affects their properties.
