Research Abstract

We have developed resistive switching devices based on conduction of metal ions on a nanometer scale. It was found that the switching mechanism of devices using oxide thin films consists of the formation of a metal filament by inhomogeneous nucleation and its dissolution due to a thermochemical reaction assisted by Joule heating. The validity of the proposed operation model was demonstrated by the fact that the temperature variation of switching behavior can be explained in terms of classical nucleation theory. Similar switching devices were achieved using conduction of metal ions in polymer electrolyte films. Moreover, switching phenomena due to light irradiation were also observed for a device using chalcogenide glass films.
