Perturbation Theory for Impurity Conduction

Abstract

After the preparatory work of the previous chapter and the general results of the formalism in Chaps. 12 and 13, a microscopic calculation of the residual resistivity due to the scattering of electrons by impurities and imperfections is quite straightforward. The starting point is the equation

$$\Phi \left( z \right) = \frac{1}{{N\left( z \right) - z}}{\chi ^T}$$

((12.1))

for the relaxation function defining the memory kernel N(z).
