Bipolar Electrochemical Mechanism for Mass Transfer in Nanoionic Resistive Memories

Getting a grip on the switching mechanism in nanoionic resistive memories: the bipolar electrochemical mechanism for mass transfer of Ag in nanoscale SiO2 is disclosed. The in-situ atomic-level experiments provide detailed evidence of the mass-transfer process under external electric fields. The mass transfer of Ag directly leads to conductive filament formation and disruption, which is responsible for the switching mechanism in nanoionic resistive memories.
