About crystal growth of hybrid bromide perovskite single crystals
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.
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.
