Abstract

Absrtact:

The attempt to obtain the data on thermodynamic parameters and equilibrium concentra- tions of disorder defects was made. Quasi-chemical model of the defects formation with allow- ance for Schottky and Frenkel defects was used. Thermodynamic parameters were calculated based on Weiser's technique. Six types of the disorder defects in II-IV-V2 and I-III-VI2 were considered. Used models, approaches and initial parameters give that the greatest concentration (∼ 1019 cm−3) and accordingly the greatest influence on properties of the crystals have defects AB or BA.
