A 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 کاملDetermination 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 کاملTheory of Low-Energy Electron Diffraction
A method for calculating the intensities of diffracted waves in low energy electron diffraction by crystals is proposed. The elastic multiple scattering is fully taken into account. The cellular method of KOHN and ROSTOKER in the band theory of metals is applied to the integral equation of the scattering by two dimensional lattices, particularly by monatomic layers. The solution is expanded in ...

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...
