Abstract
Low-energy-electron-diffraction (LEED), scanning-tunneling-microscopy (STM), and photoelectron-spectroscopy measurements have been performed on the ordered submonolayer surface reconstructions of Yb on Si(111). Two of these reconstructions, namely, 3×1 and 2×1, have been studied in detail. STM and LEED revealed that what was considered to be the 3×1 reconstruction is actually a 3×2 reconstruction. By combining STM and photoelectron-spectroscopy results from the 3×2 and 2×1 reconstructions, we conclude that the Yb atoms are adsorbed in bridge sites.Keywords
