Hopping conductivity in disordered systems
Webmobility in a disordered hopping system. We also consider the influence of “multiple hopping” of carriers between occasionally close hopping neighbours on the dc hopping conductivity. The general approach will be applied to an analytical treatment of the trap-controlled hopping and hopping conductivity at large carrier densities.
