Abstract

The most conventional way to grow centimetres sized MAPbBr₃ (MA = methyl ammonium) perovskite single crystals is the temperature rising method from dimethylformamide solution in which MAPbBr₃ shows an inverse solubility/T dependence. In the present study a well-defined crystallization procedure was provided. The collective and individual effect of the many experimental variables involved were highlighted and a set of guidelines were produced to control nucleation, crystal size and the macro/micro-morphology of the crystals. Several critical aspects connected to the process or environmental conditions, such as moisture level or total reaction time, have been revealed and investigated to ensure high products reproducibility between batches and over time. The efficient self-healing capability of MAPbBr₃ single crystals has been confirmed and exploited to induce a regeneration process.

关于杂化溴钙钛矿单晶的晶体生长

生长厘米大小的MAPbBr3 （MA =甲基铵）钙钛矿单晶的最传统方法是从二甲基甲酰胺溶液中升温的方法，其中MAPbBr3表现出反溶解度/T依赖性。在本研究中，提供了一个明确的结晶过程。强调了所涉及的许多实验变量的集体和个体效应，并制定了一套指导方针来控制成核，晶体尺寸和晶体的宏观/微观形态。与工艺或环境条件相关的几个关键方面，如湿度水平或总反应时间，已被揭示和调查，以确保批次和时间之间的高产品再现性。MAPbBr3单晶有效的自愈能力已被证实，并被用于诱导再生过程。

期刊介绍： The journal offers a common reference and publication source for workers engaged in research on the experimental and theoretical aspects of crystal growth and its applications, e.g. in devices. Experimental and theoretical contributions are published in the following fields: theory of nucleation and growth, molecular kinetics and transport phenomena, crystallization in viscous media such as polymers and glasses; crystal growth of metals, minerals, semiconductors, superconductors, magnetics, inorganic, organic and biological substances in bulk or as thin films; molecular beam epitaxy, chemical vapor deposition, growth of III-V and II-VI and other semiconductors; characterization of single crystals by physical and chemical methods; apparatus, instrumentation and techniques for crystal growth, and purification methods; multilayer heterostructures and their characterisation with an emphasis on crystal growth and epitaxial aspects of electronic materials. A special feature of the journal is the periodic inclusion of proceedings of symposia and conferences on relevant aspects of crystal growth.
