Abstrakt: An investigation is made of the conduction and the optical and galvanomagnetic properties of CdTe single crystals grown from a homogeneous melt modified by the Bridgman method at a rate of directed crystallization of 0.2 mm/h. It is established that conduction of constant-type isothermal annealing of the initial crystals in large volumes of Cd + LiCl salt melts at 900°C for 9–17 h provides additional purification from uncontrollable impurities and considerably increases the degree of compensation. An account is given of the change in conduction and the mechanism of electron scattering with change in the parameters of the impurity-center energy spectrum in the extractive purification of CdTe single crystals.
