Abstract
An analytical treatment of quasi-equilibrium carrier transport in diso rdered materials at moderate electric fields is presented. The transpo rt equation derived has the form of a conventional Fokker-Plank equati on with drift, diffusion and field-assisted diffusion terms. General f ormulae are obtained for drift mobility as well as for the coefficient s of conventional and field-assisted diffusion. The temperature depend ences of these quantities are considered for different energy distribu tions of localized states.
