Description
Summary:Neuromorphic devices that mimic the information processing function of biological synapses and neurons have at-tracted considerable attention due to their potential applications in brain-like perception and computing.In this paper,neuromorphic transistors with W-doped In2O3 nanofibers as the channel layers are fabricated and optoelectronic syner-gistic synaptic plasticity is also investigated.Such nanofiber transistors can be used to emulate some biological synaptic functions,including excitatory postsynaptic current(EPSC),long-term potentiation(LTP),and depression(LTD).More-over,the synaptic plasticity of the nanofiber transistor can be synergistically modulated by light pulse and electrical pulse.At last,pulsed light learning and pulsed electrical forgetting behaviors were emulated in 5 × 5 nanofiber device array.Our results provide new insights into the development of nanofiber optoelectronic neuromorphic devices with synergistic synaptic plasticity.
