Scanning tunneling microscopy and kinetic Monte Carlo investigation of Cesium superlattices on Ag(111)
M. Ziegler, J. Kroeger, R. Berndt +2
Cesium adsorption structures on Ag(111) were characterized in a low-temperature scanning tunneling microscopy experiment. At low coverages, atomic resolution of individual Cs atoms…
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…
Ultraviolet light emission from Si in a scanning tunneling microscope
Patrick Schmidt, Richard Berndt, Mikhail I. Vexler
Ultraviolet and visible radiation is observed from the contacts of a scanning tunneling microscope with Si(100) and (111) wafers. This luminescence relies on the presence of hot el…
Lifetimes of electrons in the Shockley surface state band of Ag(111)
M. Becker, S. Crampin, R. Berndt
We present a theoretical many-body analysis of the electron-electron (e-e) inelastic damping rate of electron-like excitations in the Shockley surface state band of Ag(111). It…
