Transient dynamics of the phase transition in VO2 revealed by mega-electron-volt ultrafast electron diffraction

The atomic pathway in the photoinduced ultrafast structural phase transition of VO2 has been a controversial problem for a long time. Here the authors, using MeV ultrafast electron diffraction, show that the melting of V-V dimers and the transformation of crystal symmetry are two processes with diff...
