Recent progress in transparent memristors

Abstract

Abstract Memristors are one of the most promising next-generation nonvolatile storage devices because of their unique structure and excellent performance. Transparent memristors with multifunctional coupling are one of the future development directions for functionally integrated electronics. Compared to other memristors, transparent memristors have enormous advantages in stability and optoelectronic devices due to their transparency. These advantages will enable transparent memristors to have more potential applications, such as in optoelectronic neuromorphic systems, artificial intelligence, and human visual systems. Therefore, it is necessary to analyze trends in transparent memristors in order to realize these applications. Here, we review three application areas : nonvolatile memory, artificial synapses, and neural networks. The resistive switching mechanism of transparent memristors is introduced through the overall and local effects. Finally, application prospects and challenges of transparent memristors are summarized, which provides an insightful guide to developing transparent electronic devices further.
