An Optogenetics‐Inspired Flexible van der Waals Optoelectronic Synapse and its Application to a Convolutional Neural Network (Adv. Mater. 40/2021)

Abstract

Optoelectronic Synapses In article number 2102980, a flexible optoelectronic synapse fabricated on 2D van der Waals (vdW) layered rhenium disulfide, which features an inherent photosensitive memory nature derived from the persistent photoconductivity effect, is presented by Yong-Hoon Kim, Jin-Hong Park, and co-workers. After in-depth analysis including density functional theory calculations on rhenium disulfide, its feasibility for a hardware neural network with learning ability is also demonstrated using a convolutional neural network composed of vdW optoelectronic synapses.
