Memristive Behaviors in Ag₂S Nano-Particles Assembly

Abstract:

A memristive phenomenon was observed in bulk silver sulfide (Ag₂S) nanoparticles assembly, obtained by a chemical reaction method. Current-voltage characteristics of memristors, pinched hysteretic loops were systematically observed in the Ag/ Ag₂S /Ag cell. According to the as-obtained stable bipolar IV plots, resistance ratio between high resistance state and low resistance state was measured to be almost 100. An electrochemical redox reaction of S on the interface between Ag electrode and Ag₂S electrolyte was proposed to explain the mechanism of the experimental phenomena.
