Design and implementation of an infrared artificial visual neural synapse based on a p-WSe 2 /n-Ta 2 NiS 5 van der Waals heterojunction

This is the authors' abstract. We don't add key points for this paper.

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.
