Abstract
The solubility and diffusivity of In in CdTe has been investigated in the temperature range 200-850 degrees C, under Cd-rich and Te-rich conditions, using a radiotracer method. The diffusivity is independent of In concentration and below 400 degrees C is also largely independent of temperature. Above 400 degrees C the solubility and diffusivity depend on both temperature and non-stoichiometry. At Te saturation D(In)=6.48*10-4exp(-1.15 eV/kT) cm2s-1and at Cd saturation D(In)=117 exp(-2.21 eV/kT) cm2s-1. The results are discussed in terms of the defect chemistry of CdTe.Keywords
