Percolation model for electrical breakdown in insulating polymers

Electrical breakdown of insulating ceramics in a high-radiation field

This report addresses a recently reported phenomenon that a simultaneous application of energetic particle radiation, electric field, and elevated temperature for an extended period of time has a permanent adverse effect on insulating ceramics, including electrical breakdown. This behavior poses a serious challenge for fusion devices, which require electrical insulators in several key component...

Simulation of electrical ageing in insulating polymers using a quantitative physical model

A quantitative physical model has been expressed in terms of features generic to electrical ageing. This has been used to simulate the evolution of damage structures during the electrical ageing of insulating polymers. During the main part of the ageing process isolated regions of damage were produced at a few extremely susceptible sites. However failure occurred via an accelerating filamentary...

Electric Field Dependence of the Time to Electrostatic Breakdown in Insulating Polymers

Effect of silane coupling agent chemistry on electrical breakdown across hybrid organic-inorganic insulating films.

Dielectric breakdown measurements were conducted on self-assembled monolayer (SAM)/native silicon oxide hybrid dielectrics using conductive atomic force microscopy (C-AFM). By depositing silane coupling agents (SCAs) through a diffusional barrier layer, SAM roughness was decoupled from chemistry to compare the chemical effects of exposed R-group functionality on dielectric breakdown. Using Weib...
