The thermal conductivity of CdTe and some solid solutions of CdTe 1− x S x and CdTe 1− x Se x ( x = 0.1 and 0.2) is studied. Measurements are made at temperatures ranging from 90 to 700 °K, on two kinds of monocrystal specimens, prepared from elements of different purity. In specimens synthetized from less pure elements, the thermal conductivity starts to increase with temperature between 300 and 400 °K, whereas in specimens obtained from elements of 99.9999 per cent purity this increase only occurs at higher temperatures (about 500 °K). The additional thermal conductivity in purer specimens may be ascribed to due to ionization of impurities. For impurities in CdTe, the values of ionization energy calculated from the temperature dependence of the thermal conductivity are comparable with those determined by other methods.
