论文摘要
金属卤化物钙钛矿最近已成为下一代光电设备的有前途的材料，这是由于其出色的内在特性。在钙钛矿晶体的生长中，底物是必不可少的，并且起着至关重要的作用。在此，已经回顾了钙钛矿晶体生长中的底物工程。特别是，强调了基于用于厚度，成核和生长速率优化的基板工程的各种修改策略和相应的机制。然后，还将讨论对底物的可改变粘附。此外，已经获得了可扩展的钙钛矿单晶薄膜的外延晶体与底物的结构相干性，并可以转移到任意底物上。底物工程还可以通过调节晶体和底物之间的应变来稳定所需的钙钛矿阶段。最后，提出了基于底物工程的钙钛矿晶体生长中的一些关键挑战和相关解决方案。这篇评论旨在指导钙钛矿晶体中底物工程的未来，以用于各种光电应用。
Metal halide perovskites have recently emerged as promising materials for the next generation of optoelectronic devices owing to their remarkable intrinsic properties. In the growth of perovskite crystals, the substrates are essential and play a vital role. Herein, substrate engineering in the growth of perovskite crystals have been reviewed. Particularly, various modified strategies and corresponding mechanism based on the substrate engineering applied to the optimization of thickness, nucleation and growth rate are highlighted. Then the alterable adhesion to substrates will also be discussed. Furthermore, applying the structural coherence of epitaxial crystals with substrate, scalable perovskite single-crystalline thin films have been obtained and can be transferred onto arbitrary substrates. Substrate engineering also can stabilize the desired perovskite phases by modulating the strain between crystals and substrates. Finally, several key challenges and related solutions in the growth of perovskite crystals based on substrate engineering are proposed. This review aims to guide the future of substrate engineering in perovskite crystals for various optoelectronic applications.
