Solution-processed lateral epitaxial growth of two-dimensional (2D) halide perovskite heterostructures, multiheterostructures, and superlattices is a daunting task because of their soft fragile ionic bonding and high intrinsic ion mobility of halide ions. Recently, these structures have been successfully developed for Pb²⁺- and Sn²⁺-based 2D halide perovskites using various large organic molecules, and its potential energy application has been shown in thin-film electrical diodes.

二极管应用卤化物钙钛矿的横向外延异质结构

固溶处理的二维（2D）卤化物钙钛矿异质结构，多异质结构和超晶格的横向外延生长是一项艰巨的任务，因为它们具有柔软易碎的离子键和卤化物离子的高固有离子迁移率。近来，已经使用各种大的有机分子成功地为基于Pb ²⁺和Sn ²⁺的2D卤化钙钛矿开发了这些结构，并且其势能应用已显示在薄膜电二极管中。
