Design and implementation of an infrared artificial visual neural synapse based on a p-WSe2/n-Ta2NiS5 van der Waals heterojunction

Inspired by human visual synapses, high performance and versatile infrared vision synapses can be achieved in the p-WSe 2 /n-Ta 2 NiS 5 van der Waals heterojunction by introducing narrow band gap materials and bias-induced band bending.
