Optoelectronic Synapses Based on Inorganic-Organic Hybrid Phototransistors

Optoelectronic synapses are desirable for avoiding hardware latency and achieving high bandwidth and low crosstalk. We utilized the trapping and de-trapping effect in the inorganic-organic heterojunction to achieve optically controlled weight modulation for synaptic functions including long-term potentiation and depression depending on the incident light wavelength. The artificial synapses with optical responsivity could implement both sensing and processing functions, promising for constructing optogenetics-inspired neuromorphic vision networks.
