Metal-surface reconstruction induced by adsorbate: Fe(110) p(2×2)-S

View publication

Abstract

Reconstruction of the Fe(110) surface by a quarter monolayer of S is shown by lowenergy electron-diffraction intensity analysis to correspond to a model in which hardsphere atoms displace to a unique jamming point. After reconstruction the S atoms sit in fourfold hollows of touching Fe atoms with S-Fe bond lengths of 2.17 and 2.36. A general construction for 2×2 reconstructions with rectangular symmetry is given and applied to this case and to Ni(001)(2×2)-C. © 1981 The American Physical Society.
