Neuromorphic Visual Systems
In article number 2303584, Ya Lin, Jiangang Ma, Haiyang Xu, and co‐workers develop a high‐performance photosensor with a tin‐doped Ga2O3 film for neuromorphic vision. Pattern recognition with an accuracy of 97.3% is obtained with the neuromorphic vision system based on the Ga2O3:Sn array. The photosensor with ultrahigh responsivity and extremely long response decay time...
Ga2O3 is an emerging wide‐bandgap semiconductor with high deep ultraviolet absorption, tunable persistent photoconductivity, and excellent stability toward electric fields, making it a promising component for neuromorphic visual systems (NVSs). However, Ga2O3‐based photosensors with high responsivity and long response decay times are required for efficient NVSs. A solution‐processed doping strategy...
