A silicon nanodisk array structure realizing synaptic response of spiking neuron models with noise

In the implementation of spiking neuron models, which can achieve realistic neuron operation, generation of post-synaptic potentials (PSPs) is an essential function. We have already proposed a new nanodisk array structure for generating PSPs using delay in electron hopping among nanodisks. Generated PSPs have fluctuation caused by stochastic electron movement. Noise or fluctuation is effectively used in neural processing. In this paper, we review our proposed structure and show fluctuation controllability based on single-electron circuit simulation.
