How optical excitation controls the structure and properties of vanadium dioxide

We combine ultrafast electron diffraction and time-resolved terahertz spectroscopy measurements to link structure and electronic transport properties during the photoinduced insulator–metal transitions in vanadium dioxide. We determine the structure of the metastable monoclinic metal phase, which ex...
