COMPOSITION OF THE EQUILIBRIUM VAPOR PHASE NUMERICAL CALCULATION IN THE CASE OF CADMIUM AND ZINC CHALCOGENIDES EVAPORATION IN A LIMITED VOLUME

The results of the equilibrium vapor phase composition numerical calculations during avaporation of Cd and Zn chalcogenide are presentied. The program is based on the electroneutralyty and avaporation equiations solution. The defects model including Frenkel defects in both sublattices and neutral antisite defect are used for calculation of CdTe composition at 973 K. The validisation of the program was carried out using the results of calculating the evaporation of CdTe with a composition corresponding to congruently evaporating at a temperature of 973 K and a exess of Te in the solid state 3.88 1016 cm-3.
