We investigated the orientation dependence of the strain effect on the dielectric property of tunable (Ba,Sr)TiO3 thin films. The strain was introduced in the differently orientated films by utilizing difference in thermal expansion coefficient between films and substrates or by applying the external stress. It was found that the dielectric property of (111) films is less sensitive to the strain as compared with that of (100) films.

研究了应变效应对（Ba，Sr）TiO3薄膜介电性能的取向依赖性。利用薄膜与衬底之间的热膨胀系数差异或施加外部应力，在不同取向的薄膜中引入应变。结果表明，（111）膜的介电性能对应变的敏感性低于（100）膜。
