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 ...

Electrically Conducting Polymers

Materials & Design, 1990
Plastics 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: Foods

2010
Electrical 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

2007
Abstract : 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.

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 ...

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

Electric Conductance

1997
The migration of colloidal soil particles in an applied electric field has been discussed in Chapter 7. Soil particles carrying electric charges invariably adsorb equivalent amounts of ions of the opposite charge. Generally there is a certain amount of free ions present in soil solution.
