| 中文摘要 | Influence of LaMnO3 layer, 0-12 nm in thickness, on photovoltaic effect (PVE) has been experimentally studied for the La0.67Ca0.33MnO3/LaMnO3/SrTiO3:Nb junction. Presence of LaMnO3 causes an obvious weakening of the PVE, demonstrated by the reduction in the carrier density excited by each photon. The interfacial barrier deduced from the PVE shows a rapid growth, from similar to 1.22 to similar to 1.45 eV, as the layer thickness increases from 0 to 2 nm, and saturates at similar to 1.5 eV above 2 nm. On the contrary, current-voltage characteristics suggest a smooth reduction in interfacial barrier with layer thickness. These results can be quantitatively understood assuming the occurrence of a notch and a spike in the conduction band edges at the interface of the junction. |
