Abstract:The optically induced ultrafast insulator-to-metal transition in vanadium dioxide has attracted world-wide interest over the last decade, both for fundamental scientific reasons and for applications.  Motivated by the application of vanadium dioxide as a potential THz modulator for silicon photonics, I describe the science behind this application, by making use of plasmonic nanoparticles both to probe the mechanism and to show the relative importance of electron injection vs electron-hole pair creation in the early-stage dynamics of the phase transition.
