Abstract
Ag is grown epitaxially on Cu(111) to form quantum wells. The resulting quantum-well states and resonances, observed with angle-resolved photoemission, exhibit shifts in energy for varying emission directions and for changing Ag-film thicknesses. The results are utilized in a determination of the Ag bulk sp-band dispersion relation near the L point in the Brillouin zone. Effective masses and the Fermi surface near the L point are deduced. The Fermi surface agrees well with that obtained earlier from de Haasvan Alphen measurements.
