用XPS分析了CdS薄膜的结构。硫化镉薄膜是用化学沉积法制备的胶体颗粒,然后再通过真空蒸发法在平面玻璃上形成的多晶薄膜。XPS分析表明CdS薄膜中的Cd3d和S2P峰值均比块状CdS向高能方向偏移了10eV。这主要是由于表面效应所致。
The structure of CdS thin film was analyzed by XPS. Cadmium sulfide thin films are prepared by chemical deposition of colloidal particles, and then by vacuum evaporation in the formation of polycrystalline thin glass film. XPS analysis showed that the CdSd and S2P peaks of CdS thin films shifted 10eV from the bulk CdS to the high energy direction. This is mainly due to the surface effect.
