Principles, fabrication, and applications of halide perovskites‐based memristors

Abstract

AbstractIn recent decades, the microelectronics industry has developed rapidly based on the von Neumann architecture and under the guidance of Moore's law. However, as the size of electronic devices approaches the limit and power consumption increases, traditional microelectronic materials and devices are facing more and more challenges. As a new type of semiconductor material, halide perovskites (HPs) have excellent photoelectric characteristics, such as high carrier mobility, controllable band structure, etc., which have been widely used in solar cells, light emitting diodes (LEDs), photodetectors, memristors, and in other fields. Among them, the memristor, as a new type of electronic device, is very promising for in‐memory computing with low power consumption by breaking the limit of von Neumann architecture. Especially, HPs‐based memristors show outstanding photoelectric response performance, low power consumption, and flexible wearability, allowing them to hold great application potential in logical operation, polymorphic storage, and neuromorphic computing, etc. In this review, we first briefly introduce the basic characteristics and preparation methods of HPs. Secondly, the development history, device structure, and performance parameters of memristors are depicted in detail. Thirdly, the resistance mechanism and application of HPs‐based memristors are discussed. Finally, the research status and development prospects of HPs‐based memristors are outlined.
