Synaptic transistor with a partially reduced graphene oxide channel for physical neural networks

We developed a synaptic transistor composed of a partially reduced graphene oxide (prGO) channel and a Nafion electrolyte, operating based on electrochemical reactions of the prGO channel, which are assisted by protons through the Nafion electrolyte. The transistor exhibits synaptic plasticity such as paired-pulse facilitation, spike-timing-dependent plasticity, and long-term potentiation/depression, in a sub-millisecond range. These superior properties of the Nafion/prGO transistor have great potential in use for the development of neuromorphic computation architectures.
