The spectral recognition is key for efficient machine vision to obtain high imaging quality of color target objects. However, the bidirectional response within a single band sensors still challenging in-site recognize objects from multi-spectral context. Here, inspired by avian eyes, we propose tetrachromatic-bidirectional synaptic transistor based on WOx/WSe2 heterojunctions with ultraviolet (UV)-photoactive floating gate CdS and realize bio-avian enhanced image improved under background. positive-synaptic responses are exhibited visible wavelength while negative UV band. Moreover, bionic-kestrel behaviors exhibited, such as object images accuracy 58% 93.1% due contribution response. This work provides an effective neuromorphic feature signatures contexts.

Abstract To address the increasing demand for massive data storage and processing, brain-inspired neuromorphic computing systems based on artificial synaptic devices have been actively developed in recent years. Among various materials investigated fabrication of devices, silicon carbide (SiC) has emerged as a preferred choices due to its high electron mobility, superior thermal conductivity, excellent stability, which exhibits promising potential applications harsh environments. In this review, progress SiC-based is summarized. Firstly, an in-depth discussion conducted regarding categories, working mechanisms, structural designs these devices. Subsequently, several application scenarios are presented. Finally, few perspectives directions their future development outlined.
