A kinetic theory for nonlinear quantum transport

It is described a kinetic theory providing bases for an analytical treatmen t of nonlinear quantum transport. It is founded on a nonequilibrium statist ical ensemble formalism, which constitutes a soundly approach for the study of dissipative many-body systems driven arbitrarily away from equilibrium. This theory is applied to the study of transport of charge in n- and p- ty pe doped polar semiconductors. Evolution of the carriers' quasitemperature and mobility as well as of the relaxation times for energy and momentum are derived. Some comparison with experimental data is done.
