Abstract :

Statement of the Problem: Memristive systems based on two-dimensional (2D) crystals such as graphene, graphene oxide, molybdenum disulphide, etc., 1-5, are considered as a new type of electronic elements with extremely low energy consumption and with ultra-high scalability for processing and storage of information. The unique electronic and optical properties of 2D crystals demonstrate the enormous potential for creating ultra-high density nano-and bioelectronics for innovative imaging systems. The purpose of this study is to develop memristors with a floating photogate so-called photomemristors2,3 based on graphene and nanocrystals. Findings: A new concept of the formation of self-assembled nanoscale photomemristive heterojunctions of graphene, graphene oxide and zinc oxide in the form of two-terminal memristors with a floating photogate for bioelectronics and optoelectronics is demonstrated. Methodology & Theoretical Orientation: Photocatalytic oxidation of graphene with nanocrystals of zinc oxide is proposed as an effective method of creating two-dimensional memristive systems with photoresistive switching for synaptic nonvolatile memory of ultrahigh density. Conclusion & Significance: Two-dimensional photomemristive systems with a floating photogate exhibit multiple states controlled in a wide range of electromagnetic radiation, and can be used as neurohybrid systems for neuromorphological calculations, image processing, and pattern recognition needed to create artificial intelligence.
