Ultrafast Hot Electron Induced Phase Transitions in Vanadium Dioxide
EPJ Web of Conferences, 2013 The Au/Cr/VO2/Si system was investigated in pump–probe experiments. Hot-electrons generated in the Au were found to penetrate into the underlying VO2 and couple with its lattice inducing a semiconductor-to-metal phase transition in ~2 picoseconds.

Novel photoinduced phase transitions in transition metal oxides and diluted magnetic semiconductors [PDF]
Nanoscale Research Letters, 2012 Some transition metal oxides have frustrated electronic states under multiphase competition due to strongly correlated d electrons with spin, charge, and orbital degrees of freedom and exhibit drastic responses to external stimuli such as optical excitation.

Femtosecond laser excitation of the semiconductor-metal phase transition in VO2 [PDF]
Applied Physics Letters, 1994 We have measured the subpicosecond optical response of a solid-state, semiconductor-to-metal phase transition excited by femtosecond laser pulses. We have determined the dynamic response of the complex refractive index of VO2 thin films by making pump-probe optical transmission and reflection measurements at 780 nm. The phase transition was found to be
