Transport in dilute Li alloys

We have made a theoretical study of electrical transport in dilute Li-based alloys with a view to understanding the observed deviations from Matthiessen's rule in the cubic phase of Li. A scattering-time solution to the Boltzmann transport equation is employed. The anisotropy in the scattering is fully accounted for since it is known to be an important mechanism for deviations from Matthiessen's rule. Also included are the dynamical nature of the impurity, the intereference between impurity and perfect-crystal scattering, and the effect of the mass change. Further, the role of the Debye-Waller factor is discussed.
