通过中子粉末衍射、透射电子显微镜和热重分析验证了具有Ni阳离子的钙钛矿结构中的A-位点缺陷的低范围。首次利用热力学方法来预测钙钛矿结构中A位缺陷的程度，引入了可用于设计先进材料的简单预测标准。
The low range of A-site deficiency in perovskite structures with Ni cations was verified by neutron powder diffraction, transmission electron microscopy, and thermogravimetric analysis. A thermodynamic approach has been utilized, for the first time, to predict the extent of A-site deficiencies within the perovskite structure, introducing simple prediction criteria that could be adopted for designing advanced materials.
