5 Dec 2002 | Journal: | Phys. Rev. B 67, 205420 (2003) DOI: 10.1103/PhysRevB.67.205420 | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall | Abstract: | We study the scanning tunneling microscopy response for magnetic atoms on open and structured surfaces using Wilson’s renormalization group. We observe Fano resonances associated with Kondo resonances and interference effects. For a magnetic atom in a quantum corral coupled to the confined surface states, and experimentally relevant parameters, we observe a large confinement induced effect not present in the experiments. These results suggest that the Kondo screening is dominated by the bulk electrons rather than the surface ones. | Source: | arXiv, cond-mat/0212120 | Services: | Forum | Review | PDF | Favorites |
