Low-frequency photodielectric phenomena in polycrystalline Pb3O4 layers

Photopolarization phenomena in the polycrystalline layers of Pb3O4 with a binder have been studied. The samples exhibited a positive photocapacitive effect, an increase in dielectric losses under illumination, and a low-frequency dispersion of dielectric parameters. Possible mechanisms of relaxation processes in the dark and under illumination and the nature of relaxators are discussed.
