Abstract

Photoelectric response in photorefractive LiNbO3:Fe crystals of different degrees of reduction is studied by means of photoinduced light scattering. Dependence of photovoltaic and diffusion parameters of the electric-charge transport versus the donor/acceptor concentration is determined from the scattering intensity distribution along the crystal polar axis. The contribution of nonequilibrium electric carriers is discussed. It is shown that the effective temperature of photoexcited electrons is nonlinearly dependent on the donor concentration.
