Abstract

Experimental evidence of the bulk photovoltaic effect in photorefractive K1-xLixTa1-yNbyO3 (KLTN) crystals is shown. The dependence of the bulk photovoltaic effect on the photorefractive impurities type is presented. The current voltage characteristic is presented for different temperatures. It was found that, in Fe-doped KLTN crystals at low temperature, the bulk photovoltaic effect is the dominant transport mechanism contributing to the photorefractive process.
