薄膜 基底温度 离子源能量 折射率 平均应力 thin films substrate temperature ion source energy refractive index average stress
摘要
在不同的基底温度和离子源能量下, 采用电子束蒸发方法在GaAs基底上分别制备了SiO2、TiO2和Al2O3光学薄膜。测量了所制备薄膜的表面应力, 并对不同离子源能量下薄膜的折射率进行了测试。结果表明, 三种光学薄膜的表面应力呈不均匀分布, 通过调节基底温度和离子源能量能有效减小薄膜应力, SiO2、TiO2和Al2O3薄膜的平均应力最小值分别为2.9, 8.4, 25.1 MPa。
Abstract
The optical thin films of SiO2, TiO2 and Al2O3 are prepared on GaAs substrates by using the electron beam evaporation method under different substrate temperatures and ion source energies, respectively. The stress distributions of these thin films are measured, and the refractive indexes of these thin films prepared under different ion source energies are also tested. The results show that, the surface stress distributions of these three kinds of thin films are non-uniform, and the substrate temperature and ion source energy can be adjusted to reduce the stresses of these thin films effectively. The average minimum stresses of SiO2, TiO2 and Al2O3 thin films are 2.9, 8.4 and 25.1 MPa, respectively.
