Journal ArticleDOI
Conductance and Kondo effect in a controlled single-atom contact.
TL;DR: Spectroscopy in the contact regime was achieved and indicated a significant change of the Kondo temperature TK, indicating that the proximity of the tip shifts the cobalt d band and thus affects TK.
Journal ArticleDOI
Controlled contact to a C-60 molecule
TL;DR: Ab-initio calculations within density functional theory and nonequilibrium Green's function techniques explain the experimental data in terms of the conductance of an essentially undeformed C60 molecule adsorbed at a pentagon-hexagon bond on Cu(100).

Conductance and Kondo effect of a controlled single atom contact
TL;DR: In this article, the tip of a low-temperature scanning tunneling microscope is brought into contact with individual Kondo impurities (cobalt atoms) adsorbed on a Cu(100) surface.
Journal ArticleDOI
Electron-plasmon and electron-electron interactions at a single atom contact.
TL;DR: The transition from tunneling to contact is investigated by detecting light emitted from Au(111) in a scanning tunneling microscope using optical spectra to reflect single and multielectron processes and their distinct evolutions as a single-atom contact is formed.
Journal ArticleDOI
Controlling the Kondo effect in CoCu(n) clusters atom by atom.

TL;DR: Clusters containing a single magnetic impurity were investigated by scanning tunneling microscopy, spectroscopy, and ab initio electronic structure calculations and demonstrate the importance of the local and anisotropic electronic structure for correlation effects in small clusters.
