Optoelectronic synapse using monolayer MoS₂ field effect transistors.

ABSTRACT: Optical data sensing, processing and visual memory are fundamental requirements for artificial intelligence and robotics with autonomous navigation. Traditionally, imaging has been kept separate from the pattern recognition circuitry. Optoelectronic synapses hold the special potential of integrating these two fields into a single layer, where a single device can record optical data, convert it into a conductance state and store it for learning and pattern recognition, similar to the optic nerve in human eye. In this work, the trapping and de-trapping of photogenerated carriers in the MoS₂/SiO₂ interface of a n-channel MoS₂ transistor was employed to emulate the optoelectronic synapse characteristics. The monolayer MoS₂ field effect transistor (FE
