Abstract The results of structural, electrical, and photoelectric investigations of phase transitions in layers of cadmium-sulfide and cadmium-telluride solid solutions synthesized under profoundly nonequilibrium conditions are reported. As a model process, the thermally activated decomposition of a CdSxTe1−x single-phase solution containing the α1 (x 1=0.4–0.6) phase was chosen. Increasing the temperature was shown to result in the formation a heterophase system with two phases α2 (x 2=0.1–0.2) and α3 (x 3=0.78–0.99). The electron diffraction patterns, the photoelectric-current spectrum, and the temperature dependences of the dark electrical conductivity in the course of and after phase transitions are reported. The results of electrical and photoelectric investigations are compared with the results of structural investigations. Changes in the dark conductivity in the course of phase transitions are shown to simultaneously account for the evolution of the density of states near the Fermi level.
