Pico-second photoelectric characteristic in manganite oxide La0.67Ca0.33MnO3 films
-
Abstract
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 1.064μm 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. -
