Recent advances in fabrication and functions of neuromorphic system based on organic field effect transistor

Abstract

The development of various artificial electronics and machines would explosively increase the amount of information and data, which need to be processed via in-situ remediation. Bioinspired synapse devices can store and process signals in a parallel way, thus improving fault tolerance and decreasing the power consumption of artificial systems. The organic field effect transistor (OFET) is a promising component for bioinspired neuromorphic systems because it is suitable for large-scale integrated circuits and flexible devices. In this review, the organic semiconductor materials, structures and fabrication, and different artificial sensory perception systems functions based on neuromorphic OFET devices are summarized. Subsequently, a summary and challenges of neuromorphic OFET devices are provided. This review presents a detailed introduction to the recent progress of neuromorphic OFET devices from semiconductor materials to perception systems, which would serve as a reference for the development of neuromorphic systems in future bioinspired electronics.
