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…
Rotation of C60 in a single-molecule contact
N. Neel, L. Limot, J. Kroeger +1
The orientation of individual C60 molecules adsorbed on Cu(100) is reversibly switched when the tip of a scanning tunneling microscope is approached to contact the molecule. The pr…
Unoccupied states of individual silver clusters and chains on Ag(111)
A. Sperl, J. Kroeger, N. Neel +4
Size-selected silver clusters on Ag(111) were fabricated with the tip of a scanning tunneling microscope. Unoccupied electron resonances give rise to image contrast and spectral fe…
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…
