Abstract
The electronic structures of a single-domain Si(001)2 × 1-K surface at saturation coverage have been studied by synchrotron radiation (SR) angle resolved photoelectron spectroscopy (ARPES). The ARPES spectra have been measured along several symmetry axes of the 2 × 1 surface Brillouin zone and surface state dispersions are depicted. Symmetry properties of upper surface-state bands are determined using the linearly polarized character of SR. The symmetries and dispersions of the upper surface states determined here are consistent with those expected for a K double-layer model.
