Current status and prospects of memristors based on novel 2D materials

Abstract

As promising non-volatile memory devices, memristors have received extensive attention since they can effectively mimic synapses and enable the fabrication of neuromorphic systems. In recent years, 2D materials have been widely used in memristors because of their unique advantages, which not only improve the performance of memristors, but also promote the applicability of memristors in flexible electronics, low-power high-temperature devices, neuromorphic computing, etc. In this review, we summarize the applications of 2D materials in fabricating memristors and their physical switching mechanisms. The challenges involved are discussed and the corresponding strategies are reviewed.
