Theory 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 کاملTime Resolved Relativistic Electron Diffraction
We report on the use of a ultrashort high brightness relativistic beam from the UCLA Pegasus laboratory RF photoinjector source for probing matter transformation at the atomic scale with sub-100 fs time resolution. The high accelerating gradient and the relativistic electron energy allow to pack more than 107 electrons in less than 100 fs bunch length, enabling the study of irreversible ultrafa...
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 کاملLow-Energy Electron Diffraction Amplitudes for a "Bare-Substrate" Model
A theory of low-energy electron dif fraction (LEED) amplitudes is developed for a model in which the crystal surface is represented by a step-function termination of the bulk crystal potential ("bare-substrate" mode l ) . The crystal is considered to be centro-symmetric and it is assumed that either the crystal has a two-fold axis of rotation normal to the surface or the primay beam is normally...
متن کاملTheory of Low-Energy Electron Diffraction II. Cellular Method for Complex Monolayers and Multilayers
The method of calculating the intensities of waves in low-energy electron diffraction (LEED) whidi was applied in Part I to monatomic layers is generalized and applied to complex monolayers and multilayers. Using the "muffin-tin" model, whidi is widely used in the band theory of metals, the wave function is expanded in spherical harmonics on the surfaces of the set of atomic spheres whidi build...
