摘要:
Photorefractive effects in LEC-grown, semi-insulating, undoped GaAs crystals were investigated. The existence of both neutral and ionized states of the EL-2 center makes this material photorefractive. However, the presence of other defects and impurities can drastically deteriorate photorefractive properties.
