Abstract

The invention provides a preparation method and application of a neural network visual perception-oriented novel memory light responder. Molybdenum disulfide nanosheets are asymmetrically deposited on a defective graphene electrode through a mask on a silicon dioxide substrate by using an ultrasonic atomization deposition method, and graphene and molybdenum disulfide are partially oxidized by heating; and an asymmetric graphene oxide / oxygen-doped molybdenum sulfide / graphene oxide device with a photovoltaic effect is formed so as to be used as a novel memory light responder for visual perception of a neural network. The invention provides a novel device for regulating and controlling the light response rate of devices at two ends by memorizing the electric flux flowing through the device, a preparation method and application thereof.

Description

technical field [0001] The present invention relates to a novel two-terminal device for neural network visual perception integrating sensing, storage and computing, and in particular to a novel memory-optical responder oriented to neural network visual perception and its preparation method and application. Background technique [0002] In recent years, with the rapid development of artificial intelligence fields such as information-based operations and intelligent robots, the demand for processing wide-spectrum image information has continued to grow, and higher requirements have been put forward for intelligent perception technology. The development of high-performance, intelligent artificial intelligence visual perception chips is a strategic commanding height for establishing a new generation of intelligent independent identification and decision-making system and developing broad-spectrum information acquisition technology for unmanned spaces such as deep sea and deep spa...
