Selenium Vacancy-Enabled 2D Bi2O2Se Optoelectronic Synapses for Neuromorphic Vision Processing.
Neuromorphic visual computing aims to fuse sensing, memory, and processing into a single hardware stack, enabling reliable analog weight updates. Defect engineering in two-dimensional (2D) semiconductors is an effective strategy for achieving such synaptic functionality. However, in most 2D materials, the defects that...
