Abstract
The initial growth of Pt on the Ni(I 10)43 x 1)-O and NiO(110) surfaces has been studied by coaxial impact collision ion scattering spectroscopy (CAICISS), low energy electron diffraction (LEED) and X-ray photoelectron spectroscopy (XPS). Prior to Pt deposition, the atomic structure of the near-surface regions of the Ni(110)-(3 x 1)-O and NiO(110) structures were studied using CAICISS, finding changes to the interlayer spacings due to the adsorption of oxygen. Deposition of Pt on the Ni(110)-(3 x 1)-O surface led to a random substitutional alloy in the near-surface region at Pt coverages both below and in excess of I ML. In contrast, when the surface was treated with 1800 L of atomic oxygen in order to form a NiO(110) surface, a thin Pt layer was formed upon room temperature Pt deposition. XPS and LEED data are presented throughout to support the CAICISS observations. (c) 2006 Elsevier B.V. All rights reserved.
