Monitoring vertical Bridgman-Stockbarger growth of cadmium telluride by an eddy current technique

The electric conductivity of indium-doped cadmium telluride (CdTe) in the temperature range 600–1080°C was 163 to 1203 Ω-1m-1.In-situ monitoring of vertical Bridgman-Stockbarger growth showed an unexpected step change in the voltage response vs height. Differential thermal analysis of CdTe showed both Cd and Te melting peaks as well as an exothermic reaction above 790°C.
