Abstract
We investigate the Ir(1 1 0)-c(2 × 4)S adsorbate system using X-ray photoelectron diffraction. As proposed by a previous structure model based on a scanning tunneling microscopy experiment, we find that sulfur atoms of this superstructure enter the second adsorption layer. In contrast to the existing structure model the adatoms do not occupy on-top adsorption sites above first-layer adatoms. We refine the proposed structure model by moving sulfur atoms of the second adsorption layer out of the on-top position. Our experimental results are compared with single and multiple scattering calculations. © 2003 Elsevier B.V. All rights reserved.
