The authors investigate the effect of the energy-dependent model densities of states on the DC conductivity of the small-polaron hopping regime in disordered systems. The DC conductivity behaviour is obtained for the high- and low-temperature cases, ignoring or taking into account correlations between bonds due to the energy of the common site.
