Low-energy electron diffraction study of the thermal expansion of Ag(111)
The temperature dependence of the first three interlayer distances of the Ag(111) surface was studied by low-energy electron diffraction (LEED) over the temperature range 128K to 723 K. The first three interlayer spacings and the effective Debye temperatures were extracted from the LEED analysis. At the lowest temperature, the first two interlayer spacings are slightly (0.5 %) contracted. All t...

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 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 ...
