Diffraction Models, Dynamical Structure Tensors, and Electron-Phonon Interaction
Abstract
A coherent exposition of the theory of scattering from a dynamic lattice, which applies to the scattering of Bloch wave electrons as well as the scattering of plane waves, is presented. This is achieved by developing a generalized diffraction model, along the lines conceived by Van Hove, appropriate for the scattering of Bloch waves. The resulting diffraction model provides a basis for treating processes controlled by electron-phonon interaction in general and subsumes the standard diffraction model results. The diffraction model origins of the standard approximate expressions used to describe electron-phonon interaction controlled processors are also revealed. Keywords: Electron scattering in crystalline and disordered metals, Electrical and thermal transport in metals, Sham-Ziman approximation, Structure factors, Diffraction models, Electron phonon interaction, X ray and neutron scattering from metals.
