IR Materials Producibility.

Abstract

The formation energy for mercury vacancy - tellurium antisite pairs is calculated. We developed a method for calculating the ionization energies of the defects in semiconductors. The electron-phonon interaction-induced band-edge shifts in semiconductors are calculated using accurate band structures. The temperature variation of gaps in GaAs (done to validate our method) and Hg(0.78)Cd(0.22)Te have been calculated and are found to agree well with experiments.
