Vacancy-vacancy, vacancy-impurity, and impurity-impurity interactions in aluminum

Physical Review B, 1974
Electronic interactions between vacancies and impurity atoms have been generally studied using the pseudopotential formulation based on the second-order perturbation theory. The distortions of the lattice around vacancies and impurity atoms were conventionally neglected because of their great complexity.

The impurity-impurity interaction in aluminum

Physics Letters A, 1973
Abstract The interaction between a Cu atom and a Sn atom in aluminum was calculated by the pseudopotential method. It is shown that there is a rather weak coupling between these different types of impurity atoms.

Simplified Impurity Calculation

Physical Review, 1954
The methods of previous papers by the authors are applied to a simplified impurity calculation. This is the case of a localized perturbation in a simple cubic lattice. We consider the effect of the perturbation on a single band which is describable in terms of a Wannier function which only has nearest neighbor interactions.

Theory of impurity scattering: Interstitial impurities

Physics of Condensed Matter, 1975
A framework for studying impurity scattering in dilute, non-magnetic, metal alloys can be developed from a knowledge of the exact electronic eigenstates of a single impurity in an otherwise perfect lattice of muffin tin potentials. Such an approach has been developed for systems in which the impurity occupies a substitutional site of the lattice, as ...
