Spin-coated silver nanocomposite resistive switching devices

A simple two-terminal resistive switching device is fabricated on the basis of a silver-based nanocomposite by means of direct processing through spin-coating technique. The work mainly focuses on the role of Ag in inducing a resistive switching in response to an applied electric field. Characterization results confirm the field-induced formation of a conductive filament along the silver clusters bridging the two electrodes, which evidences the microscopic origin of bipolar resistive switching behaviour observed in our device. Electrical and morphological characterizations performed on the device support the hypothesis of field induced filament formation. The present study evidences a simple and low-cost material, easily processable to realize logic devices exhibiting a bipolar non-volatile switching behaviour that is controllable by means of the current compliance level.
