Temperature dependent frequency tuning of NbOx relaxation oscillators

Nandi, Sanjoy; Li, Shuai (Jack); Liu, Xinjun; Elliman, Robert


This study investigates the temperature dependence of current-controlled negative differential resistance (CC-NDR) in Pt/NbOx/TiN devices and its effect on the dynamics of associated Pearson-Anson relaxation oscillators. The voltage range over which CC-NDR is observed decreases with increasing temperature such that no NDR is observed for temperatures above ~380 K. Up to this temperature, relaxation oscillators exhibit voltage and temperature dependent oscillation frequencies in the range of 1...[Show more]
