Metal-oxide interface reactions and their effect on integrated resistive/threshold switching in NbOx
Shimul Kanti Nath, Sanjoy Kumar Nandi, Shuai Li +1
Reactive metal electrodes (Nb, Ti, Cr, Ta, and Hf) are shown to play an important role in controlling the volatile switching characteristics of metal/Nb2O5/Pt devices. In particula…

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…

Current localisation and redistribution as the basis of discontinuous current controlled negative differential resistance in NbOx
Sanjoy Kumar Nandi, Shimul Kanti Nath, Assaad El Helou +4
In-situ thermo-reflectance imaging is used to show that the discontinuous, snap-back mode of current-controlled negative differential resistance (CC-NDR) in NbOx-based devices is a…
