Valence-Electron Resonances in Alkali-Metal Overlayers Observed via Photoemission Line-Shape Changes
Artikel i vetenskaplig tidskrift, 1996
Valence-electron resonances for Na overlayers on Ag(111) and Cu(111) are observed by photoemission via line-shape changes for the substrate s,p-band emission in a narrow range of photon energies. The effect is ascribed to interfering contributions to the photoelectron wave from the substrate and the vacuum barrier.
