Atom Transfer and Single-Adatom Contacts
L. Limot, J. Kröger, R. Berndt +2
The point contact of a tunnel tip approaching towards Ag(111) and Cu(111) surfaces is investigated with a low temperature scanning tunneling microscope. A sharp jump-to-contact, ra…
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…
