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…

Two-Electron Photon Emission From Metallic Quantum Wells
Germar Hoffmann, Richard Berndt, Peter Johansson
Unusual emission of visible light is observed in scanning tunneling microscopy of the quantum well system Na on Cu(111). Photons are emitted at energies exceeding the energy of the…
