Nonlinear photovoltaic effect in Sillenite photorefractive crystals
Abstract
We report on the presence of photovoltaic effect in some Sillenite photorefractive crystals and compare their behavior with that of the well known photovoltaic LiNbO3:Fe crystal. Nonlinear photovoltaic behavior of these Sillenites are also reported here for the first time and explained by the presence of shallow along with deep photovoltaic centers.
