| 摘 要： | 用真空热蒸发法在玻璃衬底制备CdTe和Cd掺杂CdTe薄膜.研究热处理和Gd掺杂量对CdTe薄膜结构、光学特性的影响.结果表明,薄膜均为立方闪锌矿结构,Gd的掺入没有改变薄膜的晶体结构,但使薄膜的晶粒尺寸减小,晶格常数和晶胞体积略有增大,并使其择优取向由220]晶向变为111]晶向.掺Gd使薄膜在可见光范围透过率增强,但对光能隙影响不大.

| Abstract: | CdTe thin films and Gd-doped CdTe thin films were prepared by vacuum thermal evaporation on glass substrates.The effect of heat-treatment and doping content of Gd on the structure,optical characteristics of CdTe films was studied.The results show that all thin films are cube sphalerite structure.Gd doping doesn't change crystal structure of thin films,but it makes average crystal size of CdTe films turn small,the lattice constant and crystal cell volume turn big appreciably,and a preferential growth orienta... |
