Photon-Memristive Device for Neuromorphic Computing

Abstract

With the development of artificial intelligence technology, the usage of perception, storage and computing integrated devices for neuromorphic computing has become a research hotspot. We have successfully fabricated a photonmemristive device with optical sensing ability, which could simulate the synaptic behaviors in the human brain. The device could receive and respond to ultraviolet light, and realize synaptic functions, such as short-term plasticity, long-term potentiation and paired-pulse facilitation. In addition, it was able to be applied in the image identification field, the recognition rate could reach 92.2%. The device still had high stability and low operating current after light pulses excitation. The two-terminal photonic memristive unit is expected to be integrated into a 3D system and have broad application prospects in the field of artificial intelligence.
