Journal ArticleDOI
Unique growth mode observed in a Pb thin film on the threefold surface of an i-Ag-In-Yb quasicrystal
TL;DR: In this paper, Pb atoms are found to adsorb at sites over a range of heights, which are explained by bulk atomic positions left vacant by surface truncation, producing three-dimensional, isolated quasicrystalline Pb structures.
Journal ArticleDOI
Azimuthal dependence of the near-edge x-ray-absorption fine structure from Ni(110)c(2×2)-S at the S K edge
TL;DR: The calculations show that the NEXAFS above the white line is determined in a complicated way by several shells of neighboring atoms, and is not simply dominated by sulfur-nickel near-neighbor scattering, and therefore complement the surface extended x-ray-absorption fine-structure information.
Journal ArticleDOI
Two- and three-dimensional growth of Bi on i-Al-Pd-Mn studied using medium-energy ion scattering

TL;DR: In this article, the authors reported the results of Bi deposition on i-Al-Pd-Mn using medium-energy ion scattering to characterize the island thickness and the structural arrangement of Bi atoms within the islands.
Journal ArticleDOI
Low-energy electron diffraction study of the surface geometry of Ni(100)–(3×3)-K+4O
TL;DR: A dynamical LEED study of the (3×3) structure which forms upon coadsorption of K and O on Ni(100) indicates that this structure is comprised of one K atom and four O atoms per (3 × 3) unit cell as discussed by the authors.
Journal ArticleDOI

TL;DR: Scanning tunneling microscopy and x-ray photoemission spectroscopy on a polygrain icosahedral Al–Pd–Re quasicrystal show the formation of the twofold surfaces with symmetry and composition expected from the bulk, indicating that the two fold surface is the most stable among all the crystallographic planes.
