Abstract

Photorefractive crystals Bi₁₂SiO₂₀ (BSO) are particular interest for applications such as spatial light modulators, image amplification and the like. Some properties are connected to distribution of space charge induced in the crystal both by an applied (or intrinsic) electric field and illumination. Many electrical and optical properties as BSO dependence on density and king of localized states. In these paper the results of study of both photoelectret and thermoelectret state (PES and TES) and intrinsic charge distribution as were are presented.
