The diffusion of nickel and of chlorine into single crystals of p-type lead telluride has been measured at 700~ When nickel and chlorine diffuse simultaneously, there is an interaction between them such that the concentration profile of the nickel exhibits a sharp minimum.

Using radio-tracer 2l0Pb, the diffusion of lead has been studied in PbTe at 700°C as a function of composition and doping level. The results indicate that the predominant cation defect is of the Frenkel type.
