Effect of quantum confinement of surface electrons on adatom–adatom interactions
2007
New Journal of Physics
Preserved Fulltext
The quantum confinement of surface-state electrons in atomic-scale nanostructures is studied by means of the Korringa-Kohn-Rostoker (KKR) Green's function method. We demonstrate that the surface-state mediated interaction between adatoms can be significantly modified by the quantum confinement of surface electrons. We show that quantum corrals and quantum mirrors constructed on metal surfaces can be used to tailor the exchange interaction between magnetic adatoms at large distances. We discuss
