This study presents a van der Waals P3HT/GaAs nanowires P-N junction combined with a Schottky junction for birdlike visual enhancement. The resulting broadband neuromorphic visual sensor (BBNVS) array exhibits non-volatile storage, low-light perception, and near-zero power consumption. In-memory sensing and computing exceeding 5 bits is achieved, and a reservoir computing system demonstrates up to 94% accuracy for color recognition and fusion visual imaging (visible and UV).
