Abstrakt: The electronic properties of self-assembled dysprosium silicide nanowires on Si(557) are studied by angle-resolved photoelectron spectroscopy. Using a toroidal electron energy analyzer, the energy surfaces of the nanostructures are imaged. At dysprosium coverages exceeding one monolayer, metallic nanowires with a two-dimensional electronic structure are formed on [111]-oriented terraces, consisting of hexagonal DySi2 monolayers or Dy3Si5 multilayers with the c-axis in [111] direction of the substrate.
