IN AND INSE DOPING INFLUENCE ON CDTE POSTMELTING EFFECT

The influence of small In or InSe (up to 10 mol. %) additions to the C dTe melt on additional endothermic effects (AEE) positions in DTA ther mograms was studied. It was observed, that both AEEs at 1392 K, typica l for pure CdTe melt, and ''own'' at T-m+(9-10) K appear in CdTe-In me lt heating curves during thermocycling. The melting of CdTe-InSe alloy s occurs step-by-step without ''own'' postmelting effects. The solid C dTe dissociation enthalpy near T-m (Delta H-diss=287+/-22kJ/mol) and t he CdTe fusion enthalpy(Delta H-f= 43,85+/-1,15 kJ/mol) were estimated on the base of the obtained DTA data.
