NbO2-based memristive neurons for burst-based perceptron
Yeheng Bo, Peng Zhang, Ziqing Luo +3
Neuromorphic computing using spike-based learning has broad prospects in reducing computing power. Memristive neurons composed with two locally active memristors have been used to…
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…
Origin of current-controlled negative differential resistance modes and the emergence of composite characteristics with high complexity
Shuai Li, Xinjun Liu, Sanjoy Kumar Nandi +2
Current-controlled negative differential resistance has significant potential as a fundamental building block in brain-inspired neuromorphic computing. However, achieving desired n…
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…
