Investigation on Chalcopyrite Semiconductors.

Abstract

A rigid ion second neighbor force constant phonon model was developed for chalcopyrites with zincblende parent compound as a limiting case. Study of zincblende to chalcopyrite mappings led to development of a Brillouin zone special point summation theory. Brout's sum rule was shown to be a limiting case of this theory. The importance of the relation between zincblende and chalcopyrite phonon deformation parameters led to development of a phenomenological model for zincblende phonon deformation model valid throughout the Brillouin zone. The techniques developed for generating this model are simpler than others published to date and are applicable to any symmetry based model. (Author)
