Abstract

The nature and control of individual metal atoms on insulators are of great importance in emerging atomic-scale technologies. Individual gold atoms on an ultrathin insulating sodium chloride film supported by a copper surface exhibit two different charge states, which are stabilized by the large ionic polarizability of the film. The charge state and associated physical and chemical properties such as diffusion can be controlled by adding or removing a single electron to or from the adatom with a scanning tunneling microscope tip. The simple physical mechanism behind the charge bistability in this case suggests that this is a common phenomenon for adsorbates on polar insulating films.

The simulated STM images reproduce all features of the experimental appearance. However a quantitative comparison of the images of Au 0 suffers from the limited ability of DFT to describe the NIR state by Kohn-Sham states.

The intrinsic line width of the 6 s -derived state could not be resolved because the energy-level spacing is too large in the finite slab calculation.
