Is there a future for LEED intensities?

  • K. Heinz
Surfaces, Interfaces, and Layer Structures

Abstract

The application of LEED intensities within surface crystallography is illuminated with respect to its today's standard, frontier and hopes. It is shown that structure determination is possible with high accuracy in case of simple surfaces. For more complex surfaces with about a handful of atoms in the surface unit-cell structural parameters are still reliably determined, however, with tremendously increasing computational amount of work. Some approximative approaches which could show a way out of the misery are described. However, importance is attached to other and newer developments of LEED as well. So the possibility to extract structural informations from diffuse intensities in case of disordered adsorption is demonstrated as well as the use of intensities to probe the critical phenomena and kinetics of surface phase transitions. Examples are given which make the future of LEED intensities appear quite promising.
