Reconfigurable in-Sensor Image Enhancement Based on Tunable Band Alignment of In <sub>2</sub> Se <sub>3</sub> /PdSe <sub>2</sub> Heterojunction
%. By synergistically leveraging electrostatic and ferroelectric fields to tune the band alignment, we achieve programmable carrier collection efficiency, leading to a gate-tunable nonlinear photocurrent response. This hardware-level nonlinearity enables dual imaging modes for adaptive imaging: a low-light signal amplification mode to boost brightness and an overexposure recovery mode to compress contrast. By implementing a programmable photoresponse into a single photodetector, our approach bypasses redundant data transmission, providing a compact and energy-efficient solution for intelligent vision systems.
