Description:
This work investigates the surface dynamics of vanadium dioxide with nitric oxide in dependence of its metal-to-insulator transition (MIT) at 68 °C. At lower temperatures VO2 has a monoclinic lattice structure which has low electrical conductance. VO2(M) is therefore considered an insulator. At higher temperature it is found in its rutile phase, which shows several orders of magnitude more electrical conductance than the monoclinic phase. VO2(R) is therefore considered a metal. In previous works it was found that when vibrationally excited NO scatters from metal surfaces, such as Au(111) an...
