Abstract
The electronic structure of ultra thin silver films deposited on a V(1Â 0Â 0) substrate is investigated by means of angle resolved photoemission spectroscopy. We focus on the details of the electronic structure related to the hybridization between the quantized film states of s-p origin and substrate electronic states. Two distinct regions of the surface Brillouin zone (SBZ) are found to be of particular importance: the SBZ center and the region that is typically more than 0.2Â Ã
â1 outside the zone center. In relation to these SBZ parts two different hybridization schemes are identified and discussed. The first one influences the parabolic curvature of the quantum well state dispersion in the proximity of SBZ center, i.e., the effective mass. The second one relates to prominent changes of the quantum well state dispersion due to the interaction with the particular substrate bulk band and dramatically affects the photoemission intensity.
