Conductive mechanisms in electrical conductive adhesives with isotropical electrical conductivity

2011 IEEE 17th International Symposium for Design and Technology in Electronic Packaging (SIITME), 2011
Electrical conductivity of electrically conductive adhesives is controlled with three mechanisms. These mechanisms are described — a phonon-electron interaction, a constriction mechanism and a tunnel mechanism. If the phonon-electron and constriction mechanisms dominate; the temperature dependence of resistivity is positive and linear, and the ...

On the Electrical Conductivity of Metals [PDF]

Proceedings of the Physical Society, 1959
The 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, 1962
THERE 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

Electrical Conduction in Chlorpromazine

Nature, 1965
WE wish to report some further results on the electrical properties of 10-dimethylaminopropyl-2-chlorophenothiazine, commonly known as chlorpromazine. Previous work1 indicated this substance to be a semi-conductor with an activation energy of 2.1 eV and a d.c. resistivity of 1.3 × 1011 ohm-cm at 16° C.

Electrical Conductivity of Graphite

Journal of the Physical Society of Japan, 1963
Theoretical 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 ...
