In-Sensor Visible and Mid-Infrared Dual-Band Perception and Computing

Abstract Machine vision in complex environments requires hardware that can integrate multispectral sensing with real-time front-end information processing. Visible light (VIS) and mid-infrared (MIR) signals provide complementary scene information, yet existing photodetectors cann...

Ultraviolet‐Induced Band Engineering in Black Phosphorus/Gallium Nitride Heterojunction Toward High‐Performance Broadband Photodetection

ABSTRACT Broadband photodetectors that combine ultraviolet sensitivity with visible and near‐infrared response are important for multispectral optoelectronic sensing. However, the performance of these photodetectors is often limited by weak interfacial carrier separation and inef...
