New Aspects of Variable-range-hopping Conductivity in Doped Polyaniline*

Temperature, T, dependence of the electrical conductivity, σ, of own-made polyaniline pellets, highly doped either by HCl or by dodecylbenzenesulphonic acid, is discussed. For the both dopants, a variable-range-hopping exponent 2/5 is found below T * ≈ 200−250 K. This result can be understood on the basis of a recent theory of Fogler, Teber and Shklovskii which takes into account Coulomb correl...

Variable range hopping and electrical conductivity along the DNA double helix.

We present a model to describe electrical conductivity along the DNA double helix. In this model, DNA is considered as a one-dimensional disordered system, and electrons are transported via variable range hopping between localized states. Thermal structural fluctuations in DNA further localize electronic wave functions, giving rise to a temperature-dependent localization length. The model quant...

Variable Range Hopping Conductivity: Case of the non-constant density of states

The variable range hopping theory has been widely used these last years to explain the electric conduction process in some biological systems as DNA. However, the experimental measurements on such systems reveal that the density of states varies strongly near Fermi level. This observation suggests that the theoretical concept of "constant density of states" near Fermi level is certainly insuffi...

Critical properties in long-range hopping Hamiltonians

Some properties of d-dimensional disordered models with long-range random hopping amplitudes are investigated numerically at criticality. We concentrate on the correlation dimension d2 (for d = 2) and the nearest level spacing distribution Pc(s) (for d = 3) in both the weak (b ≫ 1) and the strong (b ≪ 1) coupling regime, where the parameter b plays the role of the coupling constant of the model...
