Optoelectronic synapse modulates postsynaptic currents in spiking neural networks, enhancing neuromorphic vision processing.
Spiking Neural Networks This cover illustrates a van der Waals optoelectronic synapse based on a ReS2/WSe2/h-BN heterostructure, which enables bidirectional modulation of synaptic conductance through electrostatic control of the WSe2 Fermi level. This polarity-tunable plasticity allows both positive and negative postsynaptic responses, leading to highly accurate spiking neural network learning for efficient neuromorphic vision processing.
