Low energy electron diffraction studies of high index crystal surfaces of platinum

Efficient kinematical simulation of reflection high-energy electron diffraction streak patterns for crystal surfaces

An efficient program with a user-friendly graphical interface has been developed for simulating reflection high-energy electron diffraction patterns obtained on crystal surfaces. The calculations are based on a kinematical approach which considers single electron scattering events at the surface. This time-efficient approach is in most cases sensitive enough for distinguishing different structu...

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 ...

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...

Reflection high-energy electron diffraction studies of the growth of lnAs/Ga1_xlnxSb strained-layer superlattices

We have used reflection high-energy electron diffraction to study the surface periodicity of the growth front of lnAs/GalnSb strained-layer superlattices (SLSs). We found that the apparent surface lattice spacing reproducibly changed during layers which subsequent x-ray measurements indicated were coherently strained. Abrupt changes in the measured streak spacings were found to be correlated to...
