Enhanced photosusceptibility near Tc for the light-induced insulator-to-metal phase transition in vanadium dioxide.
We use optical-pump terahertz-probe spectroscopy to investigate the near-threshold behavior of the photoinduced insulator-to-metal (IM) transition in vanadium dioxide thin films. Upon approaching Tc a reduction in the fluence required to drive the IM transition is observed, consistent with a softeni...
