The nature of dielectric breakdown

Applied Physics Letters, 2008
Dielectric 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.

Dielectric Breakdown in Solids

Proceedings of the Physical Society. Section B, 1956
It is shown that already at fairly low electronic densities (of the order 1014 cm-3) an electron exchanges energy with other electrons quicker than with lattice vibrations, mainly because collisions with the latter are nearly elastic. The notation of an electronic temperature T, which in an external field is higher than the lattice temperature, is then

Theory of Dielectric Breakdown in Metal-Loaded Dielectrics

Physical Review B, 1987
We have examined a very simple model of dielectric breakdown in random mixtures of metal and dielectric.1,2,3 We expect this analysis to be relevant for an class of materials which are composed of a random mixture of metallic particles embedded in a dielectric matrix.

Dielectric breakdown toughness from filament induced dielectric breakdown in borosilicate glass

Journal of the European Ceramic Society, 2018
The dielectric breakdown strength of borosilicate glass was measured as a function of the length of a conducting filament in order to determine the critical energy release for the growth of a breakdown channel.

Dynamics of dielectric breakdown paths

Physical Review E, 2003
We investigate the dynamics and geometry of dielectric breakdown paths of needle defects of arbitrary residual resistivity in an otherwise homogeneous medium using a time-dependent electrical-circuit model. The circuit model consists of a semi-infinite lattice of capacitors in parallel with resistors that break down to a lower (residual) resistance ...

Dielectric Breakdown of Polymer Films

Journal of Applied Physics, 1966
Strong electric fields have been applied to dielectric polymer films to study field-induced mechanical stresses. For voltages near breakdown the mechanical forces are sufficient to cause localized deformation in some polymer films. Considerable field enhancement can occur at the deformation sites, leading to reduced nominal dielectric strength for the ...

A percolative simulation of dielectric-like breakdown

Microelectronics Reliability, 1998
Dielectric-like degradation of thin-film conductors is simulated up to final breakdown within a biased percolation model. As relevant indicators we take the damage pattern, current distribution, resistance variation, failure lifetime and relative resistance fluctuations.
