概要

• 論文の詳細を見る

• We present low-temperature scanning tunneling spectroscopy results of quantum-well states above the Fermi energy in thin Yb(111) metal films deposited on a W(110) single crystal. Due to their high lateral localization, they are observed as sharp peaks in the tunneling spectra. A quantitative analysis of the spectra yields the bulk-band dispersion in $\Gamma$–$L$ direction as well as quasi-particle lifetimes. Furthermore, we analyze the influence of step edges and dislocations on the quantum-well states.
