,Electron—Phonon Interaction and Electron Transport, by .〈Τ〉/.*, where ., 〈Τ〉, and .* are the electronic charge, average of the relaxation time, and the effective mass. The relaxation time or scattering time is limited by various scatterings of carriers. Among them the phonon scattering plays the most important role. In this chapter we begin with the
