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 کاملVery Low Energy Scanning Electron Microscopy
Very low energy scanning electron microscopy is introduced as a scanning version of the low energy electron microscopy, i.e. the emission electron microscopy with the sample excited by means of a parallel wave of electrons. The incident primary electrons are retarded in the cathode lens consisting of a negatively biased sample (cathode) and earthed anode. Interaction of slow electrons with soli...
متن کاملEffects of position on oxygen saturation and heart rate in very low birth weight neonates
Background: Desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. The aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. Methods: This interventional st...
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...
