A Study of Nucleation and Dynamic Phenomena of Thermal Filaments in Vanadium Dioxide.

Abstract

The switching event responsible for the breakdown of thin films of vanadium dioxide which leads to the production of thermal filaments was theoretically and experimentally studied. It was found that a critical-temperature mechanism associated with the vanadium dioxide transition temperature was responsible for the breakdown event. A scanning infrared microscope was used to examine the thermal filaments at various bias points and ambient temperatures. The filament width and peak temperature were found to be sensitive functions of these parameters. It was also found that thermal filaments could exist at temperatures very near ambient due to thermal hysteresis. (Modified author abstract)
