  • 摘要

    采用X光电子能谱(XPS)和紫外光电子能谱(UPS)研究了软X射线辐照InP所产生的表面电子态的变化．实验结果表明，软X射线的照射，对In原子影响不大，而对P原子影响很大．分析了InP的辐照效应机理，解释了产生上述影响的原因.

     

    Abstract

    Changes of surface electronic states of InP under 1 keV X-ray irradiation is studied by X-ray photoelectron spectroscopy (XPS) and ultraviolet ray energy spectroscopy (UPS). Our results show that the soft X-ray irradiation has little effect on In atoms but much on P atoms. We analysed the mechanism of irradiation and explained the major effect.
