摘要：

The (110) surface of the alloy Pt3Sn is studied by scanning tunneling microscopy, Auger electron spectroscopy, low-energy ion spectroscopy, and low-energy electron diffraction. Preferential sputtering of the surface causes depletion in Sn in the surface region. Annealing at 600 K leads to the formation of a hill-and-valley structure with {102} facets perpendicular to the close packed [(1) over bar 10] surface rows. After annealing at 1000 K large terraces are formed with a bulk-terminated structure and well-defined steps. Of the two possible terminations, i.e., pure Pt or PtSn, the Sn rich surface is clearly favored.
