Abstract In this work, we use a previously improved technique for constructing a coincident site lattice for crystals with a perovskite structure. A method has been developed for finding atomic arrangements of various elements in grain boundaries based on a specially developed algebra. Possible compositions of chemical elements for different grain boundaries, charge states of mating planes at the grain boundary, depending on its orientation, are pointed out.

钙钛矿晶体中的特殊晶界

摘要 在这项工作中，我们使用先前改进的技术为具有钙钛矿结构的晶体构建重合位点晶格。已经开发了一种基于专门开发的代数来寻找晶界中各种元素的原子排列的方法。指出了不同晶界的化学元素的可能组成，晶界处配合面的电荷状态，取决于其取向。
