Enhanced electric conductivity of polymer‐derived SiCN ceramics by microwave post‐treatment
, 2017The effect of microwave treatment on the electric conductivity and structure of a polymer-derived SiCN ceramic is studied. It is found that the conductivity of the microwave-treated sample is about 40 times higher than that of the conventional heat ...

Nonlinear electric conductivity and thermal conductivity of WS2/EPDM field grading materials
, 2017In this work, composites with different flake-like WS2 filler contents were prepared, using ethylene propylene diene monomer as matrix. The nonlinear electric conductivity of composites at 25, 50, and 80 °C was measured, and the mechanisms were analyzed.

Electrical conductivity of metals
physica status solidi (b), 1968AbstractWith the help of Kubo formula an expression for the electrical conductivity of metals is obtained within the Hartree‐Fock approximation using the method of double time temperature dependent Green's function. A simple calculation of the relevant relaxation time appearing in the expression is presented.

Conducting Polymers: Electrical Conductivity
2007Abstract : While undoped polymers are insulators, doped conducting polymers have conductivities comparable to conventional metals and semiconductors despite their polymer chain structure. Models for the doping induced insulator-metal transition and the metallic conductivity of conducting polymers are introduced.

The electrical conduction of titanomagnetites
Physica B: Condensed Matter, 1995Electrical conductivity and thermoelectric power measurements on single crystalline titanomagnetites are reported for the temperature range of 80 up to 1100 K. The results can be well explained in terms of hopping conduction in disordered systems; the conduction is governed by electron-electron and electron-titanium interactions, leading to a ...
