ZnxCd_1—xS固熔体薄膜在太阳能电池和光导传感器等光电器件的应用上已显得愈来愈重要。这种薄膜通常是采用真空蒸发和喷溅技术来制备的。Deforges等人已叙述了用溅射方法制备了ZnxCd_1—xS薄膜。Bunton和Day等也是用溅射方法制备了ZnS薄膜。虽然对光学应用来讲光能带是半导体一个很重要的参量,但是这方面可利用的资料却很少。在本实验中,为了得到光能带与组分的关系,我们研究了ZnxCd_1-xS薄膜的光吸收光谱。这种ZnxCd_1—xS薄膜是 ZnxCd_1-xS solid solution films have become increasingly important in the application of photovoltaic devices such as solar cells and photoconductive sensors. This film is usually prepared using vacuum evaporation and sputtering techniques. Deforges et al. Have described the sputtering of ZnxCd_1-xS thin films. Bunton and Day also use the sputtering method prepared ZnS film. Although optical energy is a very important parameter for semiconductors for optical applications, there is very little information available in this area. In this experiment, in order to get the relationship between light energy band and component, we studied the light absorption spectrum of ZnxCd_1-xS thin films. This ZnxCd_1-xS film is
