A STUDY OF UMKLAPP SCATTERING AND TRANSPORT COEFFICIENTS IN SIMPLE METALS.
Abstract
Two-plane-wave models for electron-electron and electron-phonon umklapp scattering, and their effect upon the transport properties of simple metals, are discussed. For the electron-electron scattering problem, a variational approach to the Boltzmann equation is used. According to the model the electron-electron scattering contribution to resistivity is as large in alkali metals as in the simple polyvalent metals that were studied, in apparent contradiction with tentative conclusions drawn from experiment. If further experiments confirm these conclusions, then electron-phonon umklapp scattering is suggested as a possible explanation. It is shown that its contribution to resistivity does not die exponentially at low temperatures in polyvalent metals, as it does in alkali metals.
