| 摘 要： | 用真空蒸发法制备了CdS薄膜,用扫描电镜、X射线衍射仪、紫外-可见光分光光度计、四探针对薄膜的形貌、结构、光电性能进行分析测试.研究结果表明,不同基片温度下所制备的CdS薄膜主要为六方相,CdS薄膜在(002)晶面有高度的择优取向;不同基片温度下的薄膜对可见光的透光率都超过70%;薄膜的电阻率随基片温度的升高而增大;基片温度为50℃时薄膜的Eg为2.41 eV;在200℃退火处理改善了CdS薄膜的质量,结晶度提高,电阻率降低,晶粒尺寸增大;基片温度为50℃时薄膜在200℃退火后的电阻率为255Ω.cm.

| Abstract: | CdS thin film was prepared by vacuum evaporation and its surface morphology,structure and photoelectric properties were tested and analyzed with scanning electron microscopy(SEM),X-ray diffraction(XRD),UV-visible spectroscopy and four-point probe method.The results showed that the CdS thin films deposited on the substrates at different temperatures are mainly of hexagonal phase with the crystal planes(002) in highly preferred orientation.The visible light transmittances of the films deposited on the substra... |
