[(a)–(d)] DFT calculations of on Cu(111). (a) Minimum energy configuration. (b) Localized, and (c) delocalized orbitals at 0.306 and 1.573 eV above . (d) Partial density of states for Ce and cage C atoms. At energy around 0.3 eV where the conductance measurements are performed [arrow in (e)] electron states localized on Ce dominate the spectrum. Electron states delocalized on the cage have energy . (e) DOS measured by STS on and on the clean substrate.
