Abstract

Self-powered ultraviolet photovoltaic effects have been investigated in metal/SrTiO₃ Schottky junctions. The absorption edge of the SrTiO₃ single crystal is about 389 nm. The peak photovoltage of the Pt/SrTiO₃ junction is about 0.50 V at when it is illuminated by a KrF excimer laser with a wavelength of 248 nm. The peak photovoltages decrease with increasing the temperature due to the strong thermal fluctuation. Moreover, the peak photovoltages almost linearly increase with an increase in the power density of the laser at . The experimental results reveal it may be useful for self-powered ultraviolet detecting sensitive devices.
