Abstract

Effects of correlation in weakly disordered systems on the density of electronic states (DOS) and the conductivity are examined in the framework of the mean field approach. As a result of the approximation, the electronic energy spectrum is changed from a free electron energy spectrum to a Hartree exchange term added energy spectrum form. Coulomb interaction is shown to give a correction to the DOS, which reduces the electronic states. Calculations of the conductivity show that, although Coulomb interaction evaluated by the mean field theory decreases the Drude conductivity, it acts as a dephasing factor for the quantum localization correction to the conductivity.
