Dielectric breakdown in solids
Digest of Literature on Dielectrics Volume 38 1974, 1974Breakdown in solids and over surfaces of solids continues to be an area of great technological interest. Understanding has improved in high field conduction of very thin, high-quality films, laser-induced damage, and in aspects of relatively low-field, long-time deterioration of dielectrics.

Dielectric Breakdown in Dielectrics and Ferroelectric Ceramics
2014Under the application of a large enough electrical field a dielectric material can respond through motion of free charge carriers, injection of mobile charge carriers from electrodes, space charge generation, and dissipation of energy in the material, all of which may contribute to the electrical failure of the material.

Dielectric Breakdown of Polyacetylene
Japanese Journal of Applied Physics, 1983Cis-(CH) x , with lower electronic conductivity, has a higher breakdown strength than trans-(CH) x , with higher conductivity. However, the breakdown strengths of both (CH) x film isomers are much lower than those of other insulating

Dielectric breakdown in solids
Advances in Physics, 1958An account is gven of the theories of intrinsic dielectric breakdown in solids, with particular emphasis on the physical process envisaged by each theory. Theories of the modified form of thermal breakdown which occurs in impulse testing are also discussed. (W.D.M.)

The nature of dielectric breakdown
Applied Physics Letters, 2008Dielectric breakdown is the process of local materials transiting from insulating to conductive when the dielectric is submerged in a high external electric field environment. We show that the atomistic changes of the chemical bonding in a nanoscale breakdown path are extensive and irreversible.

Percolation and dielectric breakdown
Proceedings of 1994 4th International Conference on Properties and Applications of Dielectric Materials (ICPADM), 2002A simple percolation model is put forward to give a qualitative analysis for intrinsic breakdown in insulating polymers. The electron's migration in polymers should be electron hopping-conduction between localized states. When the electrical field is high enough so that electron's hopping probability between localized states is increased to a threshold,

THEORY OF DIELECTRIC BREAKDOWN*
Nature, 1943A NUMBER of years ago, a general theory of electronic motion in metals was developed by F. Bloch1 and others, using the methods of quantum mechanics. Many of the results of this general theory can be applied to non-metals, and we shall see that in ionic crystals a quantitative calculation of the mean free path is possible, which is more than was ...

Thermal breakdown in dielectrics
Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1981, 1981The basic equations governing thermal breakdown are the heat flow equation equation (1) and the equation of current continuity equation (2) where the symbols have their usual meanings. The conservation of energy is expressed by Eq. 1, and it is therefore necessary.

Dielectric breakdown in continuous models of metal-loaded dielectrics
Physical Review B, 1992We develop two- and three-dimensional models for breakdown of metal-loaded dielectrics based on the breakdown of random arrays of perfectly conducting cylinders and spheres embedded in a uniform dielectric and placed in a uniform external electric field. We determine the breakdown field, breakdown-path geometry, and dielectric constant as a function of
