Insulator-to-metal Transition Of Vanadium Dioxide Explained In Study

When heated to just above room temperature, the electrical conductivity of vanadium dioxide (VO2) abruptly increases by a factor of 10,000. Experiments at Oak Ridge National Laboratory coupled with high-performance computation reveal how the unusually large lattice vibrations, which are the oscillations of atoms about their equilibrium positions, stabilize this highly conductive metallic phase. Achievement […]
