Universal behaviour of AC hopping conductivity in disordered systems

A scaling law of the form σ( ω)/ σ(0) = f[A ω/ ω(0)] is apparent in theoretical conductivities calculated in the EPA and experimental conductivities for a variety of disordered semiconductors. It follows that the behaviour of σ(ω) is primarily generic and that and the pair approximation is an incomp...

Description
Summary:A scaling law of the form σ( ω)/ σ(0) = f[A ω/ ω(0)] is apparent in theoretical conductivities calculated in the EPA and experimental conductivities for a variety of disordered semiconductors. It follows that the behaviour of σ(ω) is primarily generic and that and the pair approximation is an incomplete explanation of ω s.
