Neuromorphic Transistors Integrating Photo‐Sensor, Optical Memory and Visual Synapses for Artificial Vision Application

Abstract
Abstract In commercial artificial vision system (AVS), the sensing, storage, and computing units are usually physically separated due to their architecture and performance gaps, which thus increases the volume, complexity, and energy loss. This work develops a neuromorphic transistor integrating these different modules within one single device. Leveraging the gate‐tunable out‐of‐plane electric field, the device achieves the multi‐mode integration of photo‐sensor, optical memory, and visual synapse. When operating at negative top gate voltage (V TG ), a strong photo‐gating effect enables highly sensitive photo‐response with responsivity of ≈6.515 kA W −1 and detectivity up to ≈3.92 × 10 14 Jones. Due to the…
