Abstract

The discontinuity in the lattice periodic potential at surfaces often leads to the creation of newelectronic surface states. We developed a photoemission based Fermi surface tomography whose surfacesensitivity allowed us to quantify the charge redistribution on the Be(0001) surface. The volume enclosedby the bulklike Fermi surface is significantly reduced at the surface, consistent with the charge transfer tothe two surface states as estimated from the area within their two-dimensional Fermi contours. This resultrepresents the first quantification of the charge redistribution on a natural surface termination.
