ABSTRACT: The electronic properties of tungsten oxide (WO3)3 nanoclusters deposited on epitaxial MgO films grown on Ag(001) can be tuned and modified simply by changing the thickness of the oxide film. In particular, we show, on the basis of first principle molecular dynamics calculations, that (WO3)3 clusters on ultrathin (
