Ultralow Power Optical Synapses Based on MoS₂ Layers by Indium‐Induced Surface Charge Doping for Biomimetic Eyes (Adv. Mater. 52/2021)

摘要

Bionic Retinas Biomimetic eyes have shown great potential in the fields of visual prostheses and robotics. In article number 2104960, PingAn Hu and co-workers propose an electron-injection-enhanced indium layer to increase MoS2 synaptic device conductivity and reduce the power consumption to 68.9 aJ per spike. Furthermore, they construct a 5 × 5 In/MoS2 synaptic device array into a hemispherical electronic retina, showing the great potential in bionic retinas, robots, and visual prostheses.
