Electrical Conductivity of Graphite
Journal of the Physical Society of Japan, 1963Theoretical calculations are given for the electrical conductivity of graphite in the hexagonal layer planes. The resistivity increases with temperatures as T 1.2 between 25°K and 77°K. In the long wave-length limit, the lattice vibrations of graphite are approximatly grouped into two modes, polarization being in the layer plane in model 1, and ...

Electric conductivity in microemulsions
The Journal of Chemical Physics, 1993Microemulsions exhibit a rather sudden change of electric conductivity upon varying either composition at fixed temperature, or temperature at fixed mean composition. In literature this has been interpreted as a percolationlike process. In this paper we question this interpretation, and suggest instead that the change of conductivity is caused by a ...

, 2018 On the Electrical Conductivity of Metals
Proceedings of the Physical Society, 1959The exact formula for the electrical conductivity of a metal, derived by Kubo, Greenwood, and others, is evaluated using Van Hove's methods for quantum mechanical transport problems. The evaluation is restricted to the case of elastic scattering by impurities or lattice vibrations, but completely avoids the use of the customary random phase assumption.

Electrical Conductivity of Proteins
Nature, 1962THERE has been considerable speculation in recent years on the nature of the current carriers in electrical conductivity of proteins. Up to 1943, the prevailing opinion was that the conductivity of proteins with adsorbed water was ionic. Then Baxter1 suggested that his results were more consistent with an electronic conduction mechanism both in the dry

Electrically Conducting Polymers
Materials & Design, 1990Plastics have long been used as insulators throughout the electronics industry, but recently new classes of polymers have been discovered that have appreciable electronic conductivities. The best of these to date has a conductivity only a single order of magnitude below that of copper, while a surprising range of other polymers have conductivities just

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.

Electrical Conductivity: Foods
2010Electrical conductivity is a physical property of foods directly related to their ability to be heated by internal heat generation when subjected to an electric field. This entry analyzes the variables that can influence the value of electrical conductivity in foods and provides a review of the actual knowledge on this subject.

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.
