Anomalous Platinum and Oxygen Transport during Electroforming of NbOx Memristors
Shimul Kanti Nath, Sanjoy Kumar Nandi, Xiao Sun +9
Electroforming of metal-oxide-metal memristors is generally attributed to the creation of oxygen-vacancy filaments within the oxide, with noble metal electrodes such as Pt and Au r…
