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…
Molecular Orbital Shift of Perylenetetracarboxylic-Dianhydride
J. Kroeger, H. Jensen, R. Berndt +2
Using low-temperature scanning tunneling microscopy we find that perylenetetracarboxylic-dianhydride on Au(788) exhibits three coexisting adsorption phases. Single-molecule tunneli…
Resonator design for surface electron lifetime studies using scanning tunneling spectroscopy
S. Crampin, H. Jensen, J. Kroeger +2
We derive expressions for the lossy boundary-scattering contribution to the linewidth of surface electronic states confined with atomic corrals and island resonators. Correcting ex…
Electron dynamics in vacancy islands
H. Jensen, J. Kroeger, R. Berndt +1
The dynamics of Ag(111) surface state electrons confined to nanoscale hexagonal and triangular vacancy islands are investigated using scanning tunneling spectroscopy. The lifetimes…
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…
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…
