Holographic low-energy electron diffraction

Journal of Physics: Condensed Matter, 2001
A method for imaging of the atomic environment of the surface of a sample, characterized by the steps of: directing a beam against the surface to form an interference pattern; detecting the intensity distribution of the pattern; calculating numerical image intensity data corresponding to the intensity distribution; and reconstructing the data to form ...

Low-Energy Electron Diffraction

1981
Low-energy electron diffraction (LEED) is the most widely applied technique for investigating the surface structure of solids. After a brief discussion of the nomenclature used in surface crystallography, the fundamental aspects of LEED and its main results are described.

On the theory of low-energy electron diffraction

Physica, 1971
Abstract In this paper we give a formal description of the influence of the inner potential on the low-energy electron diffraction patterns of crystal slabs, using a general theory of diffraction outlined in a previous paper. The crystal potential is assumed to be of the muffin-tin form and is considered to have only a two-dimensional periodicity ...

The diffraction of low-energy electrons by crystals

Journal of Physics C: Solid State Physics, 1968
A formulation of the problem of low-energy electron diffraction from crystal surfaces is given using multiple scattering theory. Only elastic processes are considered. The resultant formulae are straightforward to compute and can be applied to model surfaces of arbitrary complexity, provided they are regular.

Low energy scanning electron microscopy combined with low energy electron diffraction

Surface Science Letters, 1986
Abstract An ultra-high-vacuum (UHV) scanning-electron microscope (SEM) with a field-emission gun (FEG) is operated in a low energy region from 100 eV to 3 keV. The functions of scanning low energy electron diffraction microscopy and scanning Auger microscopy have been implemented and their performance is demonstrated.

Tensor low-energy electron diffraction

Journal of Physics: Condensed Matter, 1994
The tensor low-energy electron diffraction (LEED) approximation is a perturbative approach to the calculation of LEED I-V spectra. This article reviews the theory, applications and impact of the tensor LEED approximation upon surface crystallography by LEED.

Correlation of electron self-energy with geometric structure in low-energy electron diffraction

Journal of Physics: Condensed Matter, 2011
In low-energy electron diffraction (LEED) studies of surface geometries where the energy dependence of the intensities is analyzed, the in-plane lattice parameter of the surface is usually set to a value determined by x-ray diffraction for the bulk crystal. In cases where it is not known, for instance in films that are incommensurate with the substrate,

Surface Studies by Low-Energy Electron Diffraction and Reflection High-Energy-Electron Diffraction

2012
In this chapter, we present the basic concepts of the low-energy electron diffraction (LEED) and reflection high-energy electron diffraction (RHEED) experiments. The main goal is to provide an overview of the exploitation of these instrumental methods for analyzing the surfaces of technologically important III–V compound semiconductors.
