 Abstract: Field electron energy spectroscopy and density functional calculations have been employed to characterize electronic properties of single Pt-adatoms deposited on a thin alumina film. For Pt/Al2O3/NiAl(110) strong current enhancements were measured about 1.4 eV below the Fermi energy. No features were observed for clean Al2O3/NiAl(110) and Pt/NiAl(110) in the accessible energy range. As an explanation we propose a resonance tunneling mechanism involving an occupied electronic state of the Pt adatom close to the Fermi level.
