Sažetak
The thesis contains the results of high-resolution angle-resolved ultraviolet photoelectron spectroscopy (HRARUPS) and scanning funneling microscopy (STM) investigations of the valence band electronic structure of ultra thin silver layers on a vanadium (100). The s-p and d-symmetry quantum well states have been characterized in great detail. For 1-8 monolayers (ML) Ag s-p states we found the effects of hybridization with the substrate and the enhancement and variation of the hole-phonon coupling strength with film thickness. The d-band states were found to be perfectly confined within the film presenting an ideal example of a two-dimensional system. The surface Fermi contour was determined for 1-5 ML Ag from STM measurements and correlated to the electronic structure of the system.
