Image Recognition
The non-volatile photo-memristor has a simple two-terminal architecture, in which photoexcited carriers and oxygen-related ions are coupled, leading to a displaced and pinched hysteresis in the current-voltage characteristics. c, TCAD-simulated dark/photo current of the G/M/G device for LPS, TCAD-simulated electron current densities distribution of low photoresponse state under illumination. d, TCAD-simulated dark/photo current of the G/M/G device for high photoresponse state, TCAD-simulated electron current densities distribution of LPS under illumination. a, Single-layer perceptron (SLP) neural network architecture schematics and the accuracy of the SLP classifier during training with floating-point weight and discrepant 7-level photoresponse state.
