Space-charge waves in a Bi

We studied space-charge waves caused by the competition between holes and electrons in an undoped Bi12TiO20 photorefractive crystal and generated during holographic recording with a 532 nm wavelength laser light and the reflection geometry. A non-linear relation between the velocity of the resonant space-charge waves and light intensity, as well as the photovoltaic effect, is demonstrated. The experimental data is in good agreement with the theoretical model reported here.

Abstract

We studied space-charge waves caused by the competition between holes and electrons in an undoped Bi12TiO20 photorefractive crystal and generated during holographic recording with a 532 nm wavelength laser light and the reflection geometry. A non-linear relation between the velocity of the resonant space-charge waves and light intensity, as well as the photovoltaic effect, is demonstrated. The experimental data is in good agreement with the theoretical model reported here.
