Electronic and atomic structures of ordered metal-overlayers on Si(111) and Si(001) surfaces have been investigated by angle-resolved photoelectron spectroscopy. In the VUV photon energy region, angle-resolved photoemission has given us information about surface-state dispersion, and in the soft x-ray region, angle-resolved photoemission has given us information about surface atomic geometry. Metal overlayers treated are those of elements in the periodic table of Columns Ia, Ib, IIIb, IVb, IVb/Vb and VIb; surface orders treated are 3 × 3 on the Si(111) surface and 2 × 1 on the Si(001) surface.
