Artificial synaptic devices have potential for overcoming the bottleneck of von Neumann architecture and building artificial brain‐like computers. Up to now, developing synaptic devices by utilizing biocompatible and biodegradable materials in electronic devices has been an interesting research direction due to the requirements of sustainable development. Here, a degradable photonic synaptic device...
Artificial visual systems with image sensing and storage functions have considerable potential in the field of artificial intelligence. Light‐stimulated synaptic devices can be applied for neuromorphic computing to build artificial visual systems. Here, optoelectronic synaptic transistors based on 5,15‐(2‐hydroxyphenyl)‐10,20‐(4‐nitrophenyl)porphyrin (TPP) and dinaphtho[2,3‐b:2′,3′‐f ]thieno[3,2‐b...
Inspired by the photosynthesis process of natural plants, multifunctional transistors based on natural biomaterial chlorophyll and organic semiconductors (OSCs) are reported. Functions as photodetectors (PDs) and light‐stimulated synaptic transistors (LSSTs) can be switched by gate voltage. As PDs, the devices exhibit ultrahigh photoresponsivity up to 2 × 106 A W−1, detectivity of 6 × 1015 Jones,...
Lead‐free perovskite materials are exhibiting bright application prospects in photodetectors (PDs) owing to their low toxicity compared with traditional lead perovskites. Unfortunately, their photoelectric performance is constrained by the relatively low charge conductivity and poor stability. In this work, photoresponsive transistors based on stable lead‐free bismuth perovskites CsBi3I10 and single‐walled...
