Abstract

The surface states dispersion of the Gd-induced one-dimensional chain structure on Si(111) with a 5×2 periodicity was determined by means of angle-resolved photoelectron spectroscopy(ARPES). At least three surface states are observed at the binding energy of around 1-2eV. The dispersions of these surface states resemble those of the alkali-earth metal-induced Si(111) 5×2 surface suggesting a similar surface atomic structure. Besides these three prominent surface states, another state with very weak intensity is also observed near the Fermi level; this is different from the alkali-earth metal-induced 5×2 surface in which the surface electronic state is semiconducting.
