Lateral Epitaxial Heterostructures of Halide Perovskites for Diode Application

Abstract

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.
