Schottky barrier induced asymmetry in the negative differential resistance response of Nb/NbOx/Pt cross-point devices
Shimul Kanti Nath, Sanjoy Kumar Nandi, Assaad El-Helou +5
The negative differential resistance (NDR) response of Nb/NbOx/Pt cross-point devices is shown to have a polarity dependence due to the effect of the metal/oxide Schottky barriers…

Electric field and current induced electroforming modes in NbOx
Sanjoy Kumar Nandi, Shimul Kanti Nath, Assaad El Helou +4
Electroforming is used to initiate the memristive response in metal/oxide/metal devices by creating a filamentary conduction path in the oxide film. Here we use a simple photoresis…
