Threshold switching and electrical self-oscillation in niobium oxide films

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


Electrical self-sustained oscillations have been observed in a broad range of two-terminal systems and are of interest as possible building blocks for bio-inspired neuromorphic computing. In this work, we experimentally explore voltage-controlled oscillations in NbOx devices with a particular focus on understanding how the frequency and waveform are influenced by circuit parameters. We also introduce a finite element model of the device based on a Joule-heating induced insulator-metal...[Show more]
