DOI: 10.1007/s10853-017-0882-3
Abstract: Vacancy-mediated transport drives the functionality of oxide-based nonvolatile memristive devices. Here, we report the size dependence of TiO2/Nb:STO heterojunctions for electroforming and the subsequent resistive switching process. Conductive AFM measurements suggest that the forming and… read more here.
