Exchange interaction between single magnetic adatoms
P. Wahl, P. Simon, L. Diekhoener +4
The magnetic coupling between single Co atoms adsorbed on a copper surface is determined by probing the Kondo resonance using low-temperature scanning tunneling spectroscopy. The K…
Local pressure-induced metallization of a semiconducting carbon nanotube in a crossed junction
L. Vitali, M. Burghard, P. Wahl +2
The electronic and vibrational density of states of a semiconducting carbon nanotube in a crossed junction was investigated by elastic and inelastic scanning tunneling spectroscopy…
Kondo effect of Co adatoms on Ag monolayers on noble metal surfaces
M. A. Schneider, P. Wahl, L. Diekhöner +3
The Kondo temperature of single Co adatoms on monolayers of Ag on Cu and Au(111) is determined using Scanning Tunneling Spectroscopy. of Co on a single monolayer of Ag…
Kondo temperature of magnetic impurities at surfaces
P. Wahl, L. Diekhöner, M. A. Schneider +3
Based on the experimental observation, that only the close vicinity of a magnetic impurity at metal surfaces determines its Kondo behaviour, we introduce a simple model which expla…
Phonon and plasmon excitation in inelastic electron tunneling spectroscopy of graphite
L. Vitali, M. A. Schneider, K. Kern +2
The inelastic electron tunneling spectrum (IETS)of highly oriented pyrolitic graphite (HOPG) has been measured with scanning tunneling spectroscopy (STS) at 6K. The observed spectr…
Quantum Coherence of Image-Potential States
P. Wahl, M. A. Schneider, L. Diekhöner +2
The quantum dynamics of the two-dimensional image-potential states in front of the Cu(100) surface is measured by scanning tunneling microscopy (STM) and spectroscopy (STS). The di…
