Aspects of Linear and Nonlinear Electronic Conduction in Dissipative Media
We review a general approach to the calculation of electronic transport properties under steady-state but nonequilibrium conditions. Of particular interest is the velocity acquired by an electron in a finite electric field in a polar crystal as a (nonlinear) function of the applied electric field. The effect of finite magnetic fields applied in addition to the electric field is also considered. In solving the problem use is made of a dynamic self-consistency, the significance of which is indicated by an analysis of approximate solutions satisfying the free-energy sum rule. Emphasis throughout is on the choice of what one is calculating in addition to how one is to calculate.
