Abstract
使用射频磁控溅射,在正方形石英衬底上沉积透明导电掺Al的ZnO（AZO）和Si共掺AZO（AZO：Si）薄膜.系统研究了靶-基底距离（Dst）和Si共掺对AZO薄膜电学、光学性质的影响.电阻率、载流子浓度和迁移率都强烈地依赖于靶-基底距离,随着靶-基底距离的减少,载流子浓度和迁移率都有显著的增加,电导率也随之提高.在靶-基底距离为4.5cm处,得到最低电阻率4.94×10-4Ω·cm,此时的载流子浓度和迁移率分别是3.75×1020cm-3和33.7cm2·V-1·s-1.X射线光电子能谱（XPS）、X射线衍射（XRD）和边界散射模型被用于分析载流子浓度、迁移率和靶-基底距离的关系.透射谱显示,在可见-近红外范围内所有样品均有大于93%的平均透射率,同时随着靶基距离的减少,吸收边蓝移.AZO：Si表现出可与AZO相比拟的高电导和高透射光学特性,但在热湿环境中却有着更好的电阻稳定性,这在实际使用中很有意义.
