摘要：

Thermal effects in the characteristics of photovoltaic currents of Pb(Zr, Ti)O-3 (PZT) thin films we-re studied from room temperature up to 360 degrees C. The photovoltaic currents at a steady state increased with increasing temperature and then decreased above 250 degrees C. By conducting annealing for positively or negatively poled samples, the traces of photovoltaic currents gradually became symmetric, suggesting the improvement of crystallinity of PZT thin films and/or the formation of a symmetric pair of Schottky junctions at two interfaces with electrodes. Furthermore, this suggestion was supported by the significant improvement in the characteristics of hysteresis loops upon annealing.
