STRUCTURE OF INTRINSIC POINT DEFECTS IN CDTE

Abstract

The currently available data on the composition and constants of quasi-chemical reactions of IPD formation in CdTe are analyzed. Calculations of congruently evaporating compositions and boundaries of the compound homogeneity region in various models are presented. It is shown that the model that takes into account, in addition to charged Frenkel defects in both sublattices, also a neutral defect such as antisite tellurium or cadmium divacancies has the most satisfactory agreement with the available experimental data
