Abstract

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. More information can be found in the Research Article by Byung Chul Jang, Dong-Ho Kang, and co-workers (10.1002/adfm.202519498).
