Determination of the surface structure of CeO2(111) by low-energy electron diffraction.
We determine the atomic structure of the (111) surface of an epitaxial ceria film using low-energy electron diffraction (LEED). The 3-fold-symmetric LEED patterns are consistent with a bulk-like termination of the (111) surface. By comparing the experimental dependence of diffraction intensity on electron energy (LEED-I(V) data) with simulations of dynamic scattering from different surface stru...
متن کاملStructure Analyses of Fe-based Metallic Glasses by Electron Diffraction
Nanoscale structural information of amorphous structures has become obtainable by using nanobeam electron diffraction in combination with high resolution imaging. In addition, accurate radial distribution function analysis using energy filter has also become available to know averaged amorphous structures. In this paper, we introduce some applications of these techniques, especially to several ...
متن کاملThe structure of formate species on Pd(111) calculated by density functional theory and determined using low energy electron diffraction
The structure of formate species adsorbed on Pd(111) has been determined using low-energy electron diffraction (LEED). The presence of formate species on the Pd(111) surface was established using reflection-absorption infrared spectroscopy (RAIRS). The oxygen atoms of the formate species were found to be adsorbed over surface palladium atoms with the OCO plane perpendicular to the surface. The ...
متن کاملA Low Energy Electron Diffraction Study of Surface Structures
From the low-energy electron diffraction (LEED) analysis of the (110) surface of palladium we have determined an oscillatory relaxation with respect to the bulk interlayer spacing in the two topmost layers. We used R-factors for quantitative comparison of theoretical I-V curves with the experimental data. The oscillatory relaxation of the surface Pd(110) d12 = (1.33 ± 0.05) Å, d23 = (1.44 ± 0.0...
متن کاملStructure of the hydrogen stabilized MgO(111)-(1 · 1) surface from low energy electron diffraction (LEED)
A structural study has been performed on the MgO(111)-(1 · 1) surface by low energy electron diffraction (LEED) using experimental data obtained with a delay-line-detector LEED (DLD-LEED) system to minimize electron damage. It was found that the surface is terminated by a hydroxide layer with the topO–Mg interlayer spacing equal to 1.02 Å, which is close to the spacings betweenMg andO planes in...
