Abstract
X irradiation of undoped LiNbO3 causes a photovoltaic current along the crystal c axis, which declines at low temperatures. The ESR of Nb4+ and of trapped hole centers show parallel behavior. Illuminating a ’’saturated’’ crystal with visible light produces another decaying photovoltaic current, accompanied by ESR decrease. It is concluded that valence to conduction band transitions do not contribute essentially to the photovoltaic current.This publication has 7 references indexed in Scilit:
