在倾斜的SrTiO_3衬底上观察到La0.67Ca0.33MnO_3薄膜的超快光电特性。用脉冲宽度为25ps的1.064μm激光照射钙钛矿锰氧化物薄膜，获得了皮秒(Ps)的开路光电压。光电压脉冲的上升时间为~300ps，半高全宽为~700ps。光伏灵敏度高达~500 mV/mJ。
Ultrafast photoelectric characteristic has been observed in La0.67Ca0.33MnO3 films on tilted SrTiO3 substrates. A pico-second (ps) open-circuit photovoltage of the perovskite manganese oxide films has been obtained when the films were irradiated by a 1.064 μm laser pulse of 25 ps duration. The rise time and full width at half-maximum of the photovoltage pulse are ~300 ps and ~700 ps, respectively. The photovoltaic sensitivity was as large as ~500 mV/mJ.
