Novel design for the odd-symmetric memristor from asymmetric switches

Abstract

A novel strategy, in which two same asymmetric A/B structure switch components can be combined as a symmetric A/B/A structured device, is developed to create an odd-symmetric memristor. Furthermore, the feasibility of this strategy is experimentally confirmed by a Ag₂S/Ag/Ag₂S memristor, which exhibits an odd-symmetric I–V curve with a pinched hysteresis loop.
