摘要

采用射频反应磁控溅射方法

在Si(100)和石英基片上使用双靶溅射的方法制备了Cu掺杂ZnO 薄膜。利用X射线衍射、透射光谱和光致发光光谱分析了薄膜的晶体结构及光学性质

并与密度泛函理论计算的结果进行了对比。研究结果显示:Cu掺杂ZnO薄膜均具有高的

轴择优取向

无Cu及其氧化物相关相析出

掺杂对晶格参数的影响较小

与理论计算结果一致。Cu掺杂显著改变了ZnO薄膜在近紫外及可见光波段的吸收特性

其光学带隙随着Cu掺杂量的增加有所减小

带隙宽度的变化趋势与理论结果有着很好的一致性。Cu掺杂显著降低了ZnO薄膜的发光效率

具有明显的发光猝灭作用

但并不影响光致发光的发光峰位。说明Cu掺杂导致的吸收特性的改变可能与杂质能级有关

这与能带结构计算发现的Cu-3d电子态位于价带顶附近的禁带中是一致的。
