Energy Relaxation via Acoustic Phonons in 2D and id Electron Systems

Chapter

Abstract

The processes of momentum and energy relaxation play the central role in kinetic effects. The energy dependence of the momentum relaxation rate, usually described with the relaxation time tp, determines the temperature and concentration dependence of most linear kinetic coefficients. The energy relaxation processes (ESP) are of most importance in nonlinear effects such as hot electron phenomena. ERPs are usually described in terms the energy loss rate per one electron Q(T) which is the average energy lost by an electron with effective temperature Te exceeding the lattice temperature T.† The knowledge of Q(T) allows us to determine most characteristics of hot electrons. For instance, in a system heated by stationary current, the energy balance equation
