(a) HRTEM image of OSS perovskite film. (b) Fourier transform and (c) inverse Fourier transform of the HRTEM image of OSS film. The red “T” represents misfit edge dislocations. (d) HRTEM image of TSS at 300 ℃ perovskite film. (e) Fourier transform and (f) inverse Fourier transform of the HRTEM image of TSS at 300 ℃ film. The TEM lamellas were prepared by focused ion beam (FIB).(a) OSS钙钛矿薄膜的高分辨透射电子显微镜（High-Resolution Transmission Electron Microscopy, HRTEM）图像；(b) 该OSS薄膜HRTEM图像的傅里叶变换结果；(c) 该OSS薄膜HRTEM图像的逆傅里叶变换结果，其中红色“T”标识失配刃型位错。(d) 300℃条件下TSS钙钛矿薄膜的HRTEM图像；(e) 该300℃条件下TSS薄膜HRTEM图像的傅里叶变换结果；(f) 该300℃条件下TSS薄膜HRTEM图像的逆傅里叶变换结果。本研究中所用的透射电镜试样薄片通过聚焦离子束（Focused Ion Beam, FIB）制备得到。
