Abstract

The recrystallization of CdTe powders in different fluxes was studied and the possibility to grow p- and n - type CdTe monograin powders of high conductivity was shown. It was determined that very important technological factors for creating p - type conductivity in CdTe are the cooling rate and the presence of Te in flux. NaCl content in CdCl2 flux was found to inhibit the crystal growth and to allow for doping CdTe with Na that acts as an effective acceptor impurity in CdTe. The region of most effective added Na concentrations was found.
