Abstract

Picosecond photovoltaic effect in miscut Nb-doped SrTi[O.sub.3] single crystal observed under ultraviolet pulsed laser irradiation at ambient temperature without an applied bias is reported. The observed 10%-90% rise time and the full width at half maximum are 828 and 670 ps is explained based on terrace structure model.
