Recent progress on optoelectronic synaptic devices [PDF]

SCIENTIA SINICA Informationis, 2020
Neuromorphic (brain-like) computing has great potential to solve the von Neumann bottleneck due to its self-adaptive learning, high-parallel computing capability, and low-power consumption. Realization of neuromorphic computing depends on the development of synaptic devices that mimic biological synapses.
