The temperature dependence of photoretiactive effect in semiinsulating semiconductive material Cr: GaAs was investigated by CHENG Li-jen et al., and they thought that the band gap of conventional oxide photorefractive crystal was too wide, so it is difficult to observe the temperature dependence of photorefractive effect in a general experimental condition. But the point of view has been proved not true by our experiment展开更多
