Abstract / Description:The electrons of the surface states on the (I 11) surfaces of
the noble metals An, Ag, and Cu form a quasi-two-dimensional
(2D) free electron gas which is confined to the first few
atomic layers at the crystal surface. They are scattered by the
potential associated with surface defects, e.g. impurity atoms,
adatoms, or step edges, leading to quantum-interference
patterns in the local density of states around these defects,
We have used the quantum-interference phenomena to
quantitatively measure the electron phase-relaxation length and
to probe long-range adsorbate interactions.
