| Abstract: | It has been found by LEED and work function measurements that the presence of a fractional monolayer of Cs increased the oxidation rate of a Ni(100) surface by about thirteenfold. The NiO formed in two crystallographic orientations depending on the initial Cs coverage. Work function measurements suggest that in the enhanced oxidation the Cs atoms remained on top of the oxide. |
