UNSPECIFIED. (1997) Structural study of Rb and Cl coadsorption on Cu(111): A case of overlayer compound formation. JOURNAL OF PHYSICS-CONDENSED MATTER, 9 (22). pp. 4593-4602. ISSN 0953-8984Full text not available from this repository.
A structural study of the adsorption of Rb on a Cu(111)(root 3 x root 3)R30 degrees-Cl surface has been conducted using normal-incidence x-ray standing-wavefield absorption at both the CI and Rb surface atoms. The results indicate reaction of the coadsorbates to form an overlayer of approximately 1.2 ML of RbCl(100) which is essentially incommensurate with the substrate. The RbCl-Cu outermost layer spacing is similar to that seen for pure Rb adsorption on Cu(111). This RbCl layer is spread over the surface and not agglomerated into thicker islands. The results are consistent with prior characterization of the system by Auger electron spectroscopy and temperature-programmed desorption, and with STM studies of NaCl deposition on Al(111).
