Abstract

Abstract: Lead halide perovskites have attracted increasing attention in photovoltaic devices, light‐emitting diodes, photodetectors, and other fields due to their excellent properties. Besides optoelectronic devices, growing numbers of studies have focused on the perovskite‐based electrical devices in the past few years, such as transistors and resistive random access memories (RRAMs). Here, this article summarizes the recent progress the researchers have made of RRAM devices. Primarily, the working mechanism and the key parameters of RRAM are introduced. Generally, the working principles, including the conductive filament model (containing the types of the model of the metal cations‐induced filament and the model of the ions migration in bulk), the interface effect, and the electronic effect are the origins of the RRAM behaviors, and hence, various factors that affect the device performance are explored. Then, RRAMs based on organolead halide perovskite and all‐inorganic perovskite are discussed in terms of different structures, different compositions, and different fabrication methods. Finally, a brief conclusion and a broad outlook are given on the progress and challenges in the field of perovskite‐based RRAMs. Abstract : The latest progress of perovskite resistive random access memory (RRAM) devices is summarized. In this review, the working mechanism of perovskite RRAM is discussed, including different conductive filament models. Meanwhile, RRAMs based on organolead halide perovskite and all‐inorganic perovskite are discussed. In addition, a brief summary is given on the progress and challenges in the field of perovskite‐based RRAM.
