Ambiguous Role of Growth-Induced Defects on the Semiconductor-to-Metal Characteristics in Epitaxial VO2/TiO2 Thin Films
(2018)Controlling the semiconductor-to-metal transition temperature in epitaxial VO2 thin films remains an unresolved question both at the fundamental as well as the application level. Within the scope of this work, the effects ...

Effects of W6+ doping of TiO2 on the reactivity of supported Rh toward NO: Transient FTIR and mass spectroscopy studies
(1997)The transient adsorption and dissociation of NO over Rh supported on undoped and W6+-doped TiO2 in the temperature range of 25-450°C has been studied by FTIR and mass spectroscopy. It was found that at 25 °C three kinds ...
