摘要: A structural study of the adsorption Rb on a - Cl surface has been conducted using normal-incidence x-ray standing-wavefield absorption at both and atoms. The results indicate reaction coadsorbates to form an overlayer approximately 1.2 ML RbCl(100) which is essentially incommensurate with substrate. RbCl Cu outermost layer spacing similar that seen for pure Cu(111). This spread over not agglomerated into thicker islands. are consistent prior characterization system by Auger electron spectroscopy temperature-programmed desorption, STM studies NaCl deposition Al(111).
