Phase diagram of the ultrafast photoinduced insulator-metal transition in vanadium dioxide

We use time-resolved terahertz spectroscopy to probe the ultrafast dynamics of the insulator-metal phase transition induced by femtosecond laser pulses in a nanogranular vanadium dioxide (VO sub(2)) film. Based on the observed thresholds for characteristic transient terahertz dynamics, a phase diagr...
