Abstract:
The surface topog. and local surface work function of ultrathin MgO(001) films on Ag(001) have been studied by noncontact at. force microscopy (nc-AFM) and Kelvin probe force microscopy (KPFM). First principles calcns. have been used to explain the contrast formation of nc-AFM images. In agreement with literature, thin MgO films grow in islands with a quasi rectangular shape. Contrary to alkali halide films supported on metal surfaces, where the island heights can be correctly measured, small Mg...     »
