Controlling the Kondo Effect in CoCu_n Clusters Atom by Atom
N. Neel, J. Kroeger, R. Berndt +3
Clusters containing a single magnetic impurity were investigated by scanning tunneling microscopy, spectroscopy, and ab initio electronic structure calculations. The Kondo temperat…
Quantized Conductance of a Single Magnetic Atom
N. Neel, J. Kroeger, R. Berndt
A single Co atom adsorbed on Cu(111) or on ferromagnetic Co islands is contacted with non-magnetic W or ferromagnetic Ni tips in a scanning tunneling microscope. When the Co atom b…
Conductance and Kondo effect of a controlled single atom contact
N. Neel, J. Kroeger, L. Limot +3
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. A smooth transitio…
Phase coherence length and quantum interference patterns at step edges
S Crampin, J Kroeger, H Jensen +1
The accepted approximation used to describe quantum interference patterns at steps is shown to be incorrect. As a result, electron lifetimes determined using it are in error by a f…
Surface-State Localization at Adatoms
L. Limot, E. Pehlke, J. Kroeger +1
Low-temperature scanning tunneling spectroscopy of magnetic and non-magnetic metal atoms on Ag(111) and on Cu(111) surfaces reveals the existence of a common electronic resonance a…
Stark effect of the Au(111) and Cu(111) surface states
J. Kroeger, L. Limot, H. Jensen +2
We present a low-temperature scanning tunneling spectroscopy study of the Au(111) and of the Cu(111) surface states showing that their binding energy increases when the tip is appr…
