Abstract

Five nominally undoped BaTiO3 crystals, processed at oxygen partial pressures of 1, 10−5, 10−8, 10−11, and 10−14 atm at 900 °C, were fabricated and systematically investigated. The compensation point was found to be near the annealing level of 10−10-atm oxygen partial pressure. Annealing can vary dark conductivity, the effects of deep–shallow traps and hole–electron competition, and photorefractive properties such as two-beam coupling and response time.
