Abstract / Description:The electronic structure of a Pb overlayer on Ag(111) has been studied
by angle-resolved photoemission spectroscopy. We identify three p
bands. While the p(xy) bands are sharp and closely resemble the
corresponding bands of a free-standing Pb layer, the p(z) band is
strongly spread in energy and momentum. Tight-binding calculations of
the electronic structure combined with structural calculations using
the embedded atom method indicate a symmetry dependent hybridization
with the Ag(111) surface. We propose a symmetry selective, surface
state mediated coupling to the bulk continuum which results in a
broadened line shape for the p(z) band only.
