Conventional neuromorphic vision systems suffer from architectural fragmentation, wherein sensing, memory, and processing are distributed across discrete modules, causing high latency, energy waste, and poor dynamic adaptability. Here, we present a wavelength-driven trimodal field-effect phototransistor (TriM-FEP) ba...
Bipolar photoresponse photodetectors enable spectral discrimination and optical logic, but conventional devices often suffer from poor stability and complex fabrication. Here, we report a fully solid-state, chip-scale BaTiO3/ZnO heterojunction photodetector with a simple structure, compact size, and precise wavelength...

Polarization-sensitive self-powered ultraviolet photodetectors are of great significance for advanced target recognition, machine vision, and artificial intelligence, particularly in complex optical environments where multidimensional information extraction is critical. We report a self-powered photodetector exploiting...
