Bioinspired Artificial Visual System Based on 2D WSe₂ Synapse Array (Adv. Funct. Mater. 41/2023)

Bioinspired Artificial Visual System In article number 2303539, Ye Zhou, Su-Ting Han, and co-workers report a 2D WSe2-based retinal perception array that demonstrates an artificial vision system integrating sense and memory visual information. Highly linearly symmetric synaptic plasticity can be achieved based on the modulation of carrier types in WSe2 with different thicknesses, facilitating a high level of training accuracy for optical neural networks.
