摘要：

We investigated electrical properties of a La0.85Sr0.15MnO3 magnetic semiconductor through observation of photoinduced current and electron-beam-induced current (EBIC) across the Al/(100)SrTiO3/(100)La0.85Sr0.15MnO3 metal-insulator-semiconductor (MIS) structure at room temperature. The test specimens were prepared by the Ar-F excimer laser ablation technique. According to the current flowing direction, it was observed that the La0.85Sr0.15MnO3 band bends downward at and near the interface. Furthermore, from determination of the flat-band condition, the work function of (100)La0.85Sr0.15MnO3 epitaxial film was estimated to be similar to 4.8 eV.
