Abstract

By exploiting those novel transport phenomena at nanoscale, the nanochannel system has shown electrically maneuverable conductance, suggesting the potential usage as neuromorphic devices. However, several critical features of biological synapses, i.e., the memorable and gradual conductance modulation, were seldom reported in the system. In this work by imposing room-temperature ion liquid (IL) and KCl solution into the two ends of nanochannel system, we demonstrate that this electrical manipulation of nanochannel conductance becomes nonvolatile and capable of mimicking the analog behaviors of synapses. The mechanism of gradual conductance tuning is identified as the voltage-induced movement of the interface between the immiscible RTIL and KCl solution according tofluorescencetechnique.
