Dynamical low energy electron diffraction methods
Journal of Physics C: Solid State Physics, 1975The authors present and discuss theoretical techniques that considerably increase the power of dynamical leed calculations, particularly in the layer treatment of surfaces. Their wide applicability makes them especially suitable for surface structural determination.

Pump-probe low-energy electron diffraction
SPIE Proceedings, 1995We present a time-resolved pump-probe low energy electron diffraction experiment to study the dynamics of surface phase transitions. An ultrashort laser pulse heats a surface on a picosecond time scale, and a time-delayed, photogenerated electron pulse probes the resultant surface dynamics by diffraction.

Tensor low-energy electron diffraction
Journal of Physics: Condensed Matter, 1994The 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.

Low-Energy Electron Diffraction
1981Low-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.

Systematic Absences in Low Energy Electron Diffraction
Physica Status Solidi (a), 1978The “cluster-embedded chain”-method is applied to calculate extinction rules valid for sharp and diffuse LEED-reflections in ordered and disordered crystal surfaces. Besides the wellknown absences due to glide planes with a translational component parallel to the surface, there are others due to translations vertical to it.

Ion-induced low-energy electron diffraction
Physical Review A, 2004${\mathrm{H}}^{+}$ and ${\mathrm{He}}^{+}$ ions with an energy of $25\phantom{\rule{0.3em}{0ex}}\mathrm{keV}$ are scattered under a grazing angle of incidence from a clean and flat $\mathrm{Cu}(001)$ surface. For specific azimuthal orientations of the crystal surface with respect to low index directions in the surface plane we observe the ion induced ...

Low energy electron diffraction rocking curves
Surface Science, 1969Abstract The variation of specularly reflected beam intensity with angle of incidence and incident beam energy from the (110) surface of a tungsten single crystal for incident electron energies in the 300–600 eV range and for angles of incidence within 15° of the surface normal was found to have a structure that could only be explained in dynamical ...
