摘 要: | 研究了用阳极氧化法制备的Al_2O_3膜/InP和自身氧化膜/InP两种MIS结构的组分分布和电学性质,AES、I-V、C-V和DLTS等测试结果表明,Al_2O_3/InP结构的性能更为优越.用DLTS方法发现这两类样品都具有峰值能量为Ec-Es=0.5eV、俘获截面为~10~(-15)cm~2的连续分布的界面电子陷阱.认为该电子陷阱与磷空位缺陷有关.

The Properties of Anodic Oxide AI_2O_3/lnP and Native Oxide/lnP Interfaces |
| |
Abstract: | The composition profile and electrical properties of anodic oxide Al2O3/InP and native oxide/InP MIS structures were studied. A variety of measurements, such as AES, I-V, C-V and DLTS, were performed, showing that the Al2O3/InP structure is better than that of oxide/InP. It has been discovered by DLTS that the two kinds of samples exhibit continuously-distributed interface electron traps with a peak energy of Ec-Es = 0.5eV and a capture cross-section of-10-15cm2. We consider that the peak energy is probably related to the defect of P vacancy. |
