Hybrid C8-BTBT/lnGaAs nanowire heterojunction for artificial photosynaptic transistors
文献摘要：
The emergence of light-tunable synaptic transistors provides opportunities to break through the von Neumann bottle-neck and enable neuromorphic computing.Herein,a multifunctional synaptic transistor is constructed by using 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene(C8-BTBT)and indium gallium arsenide(InGaAs)nanowires(NWs)hybrid hetero-junction thin film as the active layer.Under illumination,the Type-Ⅰ C8-BTBT/lnGaAs NWs heterojunction would make the dissoci-ated photogenerated excitons more difficult to recombine.The persistent photoconductivity caused by charge trapping can then be used to mimic photosynaptic behaviors,including excitatory postsynaptic current,long/short-term memory and Pavlovi-an learning.Furthermore,a high classification accuracy of 89.72％can be achieved through the single-layer-perceptron hard-ware-based neural network built from C8-BTBT/lnGaAs NWs synaptic transistors.Thus,this work could provide new insights in-to the fabrication of high-performance optoelectronic synaptic devices.
