Self-oscillation up to 9 MHz based on voltage triggered switching in VO2/TiN point contact junctions

We demonstrate self-sustaining electrical oscillations with frequency of MHz range based on out-of-plane voltage-triggered switching in VO2 thin films grown on conductive layers. VO2 films deposited by a reactive sputtering method at a low temperature of 250 °C on conductive TiN layers showed therma...
