Conductivity of p-Si and p-Ge is considered for two band model with due regard for mutual drag of light and heavy holes. It is shown that for small and moderate temperatures this drag sig-nificantly d...
We present an ab-initio based kinetic Monte Carlo model for ionic conductivity in single crystal yttria-stabilized zirconia. Ionic interactions are taken into account by combining density functional t...
Conductivity of monolayer and two-layer graphene is considered with due regard for mutual drag of band elec-trons and holes. Search of contribution of the drag in conductivity shows that this effect c...
We suppose and develop quantitative simple model of polymer lm conductivity. This model can be seen as a further development of ideas of Vlasov, Apresyan et al [1]. The main point of the model is th...
Systematic conductivity measurements near TC in granular Ag-doped YBa2Cu3O7􀀀d superconductors are presented. Silver doped YBa2Cu3O7􀀀d samples were produced by different routes and ch...
In this work we report on conductivity fluctuation measurements in polycrystalline samples of the Er1−xPrxBa2Cu3O7−d superconductor (x =0.00, 0.05 and 0.10). Samples were prepared by a sta...
The electrical properties of 0.65Pb(Mg1/3Nb2/3)O3-0.35(PbTiO3) ceramics over a wide range of frequencies (102–106 Hz) and temperatures (30–225∘C) were studied using impedance spectroscopy ...
2002Vol.37No.5pp.619-622DOI: The c-Axis Infrared Conductivity of a dx2-y2 -Wave Superconductor with the Hopping Assisted by the Spin Fluctuations LOU Ping,1,2 CAO Lie-Zhao,1 and W...

An analysis and brief discussion of experimental ionic conductivity s and activation energy EA in the binary rubidium and cesium silicate systems is presented, exemplified on 23 and 30 glasses respect...
We studied the effect of superconducting fluctuations on the electrical conductivity of granular samples of Y1¡xPrxBa2Cu3O7¡d superconductors, with x =0.01, 0.03, 0.05, 0.07 and 0.10. Samp...
Polypyrrole (PPy) was prepared by a chemical method by using oxidizing agents ferric chloride and potassium persulphate, both as films and pellets. The effect of various variables-such as aging of the...
KHCO3 compound was characterized in three principle realms: for its dielectric properties as a function of temperature and frequency in the ranges 300--370 K and 50 Hz to 1 MHz, respectively; bulk con...
The ac conductivity and dielectric properties of glassy system SexTe79 - xGe21, with x = 11, 14, 17 at.%, has been studied at temperatures 300 to 450 K and over a wide range of frequencies (50 Hz to 5...
Recently, a new approach has been proposed for the correlated barrier hopping (CBH) model where the ac relaxation time is thought to obey the Meyer-Neldel (MN) rule. This approach gives quantitative a...
