Abstract
Diffusion and solubility of Fe in Bridgman grown CdTe crystals were studied by the radiotracer method (55Fe+59Fe) in the 800 - 1270 K temperature range at different Cd vapor pressures. Fe 'supersolubility' phenomenon was fixed at long annealing. Electrical and magnetic properties measurements on crystals with CFe approximately equals 1018 minus 1020 at/cm3 were performed. High-temperature (850 - 1100 K) Hall-effect measurements didn't reveal increased electron concentrations in comparison with undoped CdTe. Thermal annealing of some samples under high PCd leads to high resistivity of inner parts of the sample ((rho) approximately equals 1010 (Omega) X cm) at 300 K. The measured magnetic susceptibility temperature dependencies and its anisotropy are discussed in the framework of different dopant states in the CdTe lattice.
