Variation in the defect structure of p-CdTe single crystals at the passageof the laser shock wave

Variations in the minority-carrier lifetime, photoluminescence spectra, dar k current and photocurrent temperature dependences of high-resistivity p-Cd Te crystals under the action of the laser shock wave are investigated. It i s shown that the variations in the aforementioned characteristics during th e passage of the shock wave are defined by the generation of the nonequilib rium carriers from deep centers, and, after that, the variations are define d by the formation of intrinsic defects and their subsequent interaction wi th the defects existing in the initial crystals.
