摘要：

Photoconductivity (Po and thermally stimulated conductivity (TSC) were investigated on some single-crystal perovskite oxides. Using PC spectral dependence, band gap and impurity-level depths were found. The TSC method gave further information about the energy spectrum of local levels. Due to a significant PC and deep local levels, a photoelectret state was achieved in crystals of some compounds. Illumination of lead titanate crystals by light from the intrinsic photoconductivity region was found to induce screening of spontaneous polarization by nonequilibrium carriers. © 1978, Taylor & Francis Group, LLC.
