外文标题：Graphene/F16CuPc synaptic transistor for the emulation of multiplexed neurotransmission

外文摘要：We demonstrate a bipolar graphene/F16CuPc synaptic transistor(GFST)with matched p-type and n-type bipolar prop-erties,which emulates multiplexed neurotransmission of the release of two excitatory neurotransmitters in graphene and F16CuPc channels,separately.This process facilitates fast-switching plasticity by altering charge carriers in the separated chan-nels.The complementary neural network for image recognition of Fashion-MNIST dataset was constructed using the matched relative amplitude and plasticity properties of the GFST dominated by holes or electrons to improve the weight regulation and recognition accuracy,achieving a pattern recognition accuracy of 83.23%.These results provide new insights to the construc-tion of future neuromorphic systems.
