Application of Multiple Scattering Theory to Surfaces and Extended Defects

ABSTRACTThis article presents a brief overview of applications of multiple scattering theory to surfaces and extended defects. Discussion is given of some key issues and their practical status, and this discussion is related to the papers in the session which covered this topic at Symposium V.

Korringa-Kohn-Rostoker Electronic Structure Method for Space-Filling Cell Potentials

ABSTRACTThe multiple scattering theory (MST) method of Korringa, and of Kohn and Rostoker for determining the electronic structure of solids, originally developed in connection with potentials bounded by noa-overlapping spheres (Muffin-tin (MT) potentials), is generalized to the case of space-filling potential cells of arbitrary shape through the use of a variational formalism. This generalized version of MST retains the separability of structure and potential characteristic of the application of MST to MT potentials. However, in contrast to the MT case, different forms of MST exhibit different convergence rates for the energy and the wave function. Numerical results are presented which illustrate the differing convergence rates of the variational and nonvariatonal forms of MST for space-filling potentials.
