对卤化物钙钛矿的研究在过去十年中爆炸式增长，因为它们具有显着的光电特性。随着卤化物钙钛矿材料的成熟，越来越多的努力致力于将其开发成器件，并且需要深入了解其从原子到系统水平的物理和功能特性。对卤化物钙钛矿材料的深入理解的需要是特别关键的，因为它们目前受到它们对界面和本体分解以及相变反应的敏感性的阻碍，尽管它们经常归因于缺陷容限或“自我修复”能力。它们对扰动的敏感性也意味着卤化物钙钛矿在表征其基本和技术特性时通常需要特别小心，这正是因为材料在许多环境和电磁应力下可能发生变化，包括许多传统表征方式中固有的变化。这期特刊聚焦于钙钛矿表征的洞察力和机会，从原子分辨率显微镜的最新进展到新方法，
Research into the halide perovskites has exploded over the past decade as their combination of remarkable optoelectronic properties have come to light. As halide perovskite materials come of age, increasing effort is being dedicated to their development into devices, and an in-depth understanding of their physical and functional properties spanning from the atomic to system levels is required. The need for deeper understanding of halide perovskite materials is especially critical because they are currently hampered by their sensitivity to interfacial and bulk decomposition and phase transformation reactions despite their often-ascribed defect tolerance or “self-healing” capabilities. Their sensitivity to perturbations also means that halide perovskites often require special care in characterization of their fundamental and technological properties, precisely because changes in the material are possible under a host of environmental and electromagnetic stressors, including many that are inherent in traditional characterization modalities. This special issue focuses on insights and opportunities in the characterization of perovskites, ranging from recent advances in atomic-resolution microscopy, to new approaches
