Abstract
Non-steady-state photocurrent measurements are carried out with a n-ty pe photorefractive KNbO3:Fe crystal at the light wavelength 488 nm. Sp atial frequency dependent measurements yield the effective trap densit y. From the dielectric relaxation time for different crystal orientati ons we deduce the mobility ratios for charge carrier migration paralle l to the a-, b- and c-axis.
