Photoelectric Characteristic of La0.9Sr0.1MnO3/SrNb0.01Ti0.99O3 p-n Heterojunctions |
| |
| Abstract: | Good rectifying current-voltage characteristics and nanosecond photoelectric effects are observed in the p-n hereto junctions of La0.9Sr0.1 MnO3/SrNb0.01 Ti0.99O3 fabricated by laser molecular beam epitaxy. The rise time is about 26ns and the full width at half maximum is about 125ns for the open-circuit, photovoltaic pulses when the La0.9Sr0.1MnO3 film in the heterojunction is irradiated by a laser operated at wavelength 308nm with pulse duration of about 25 ns. A qualitative explanation is presented, based on an analysis of the photoelectric effect of p-n hereto junction. |
