Abstract
En 中文
The pursuit of energy-efficient, real-time artificial vision systems relies critically on advancing in-sensor computing hardware. Conventional p–n junctions—a cornerstone of optoelectronics—lack reconfigurable responses, while emerging reconfigurable alternatives typically require complex multi-gate control, hindering scalability. Here, an in-sensor artificial vision system based on a single-gated, reconfigurable WSe2 photodetector is presented with an asymmetric ferroelectric architecture. The device enables dynamic rectification tuning, achieving an ultrahigh rectification ratio (2 × 10⁶), near-ideal diode factor (n = 1.45), and reconfigurable bidirectional photoresponse, all controlled via a single gate. Leveraging this gate-tunable photoresponse, it demonstrates optoelectronic logic operations and multiple retinal-inspired in-sensor image preprocessing functions. By unifying reconfigurability with simple single-gate control, the design provides a foundation for energy-efficient, real-time vision systems in autonomous robotics and edge AI.
