The Role of Interfaces in Performance, Degradation, and Breakdown of Non-Linear Dielectrics Under Extreme Conditions
Abstract
A vastly improved, multi-disciplinary (linked physical, chemical, structural, electrical) understanding of how metal-dielectric, grain-boundary, and domain-boundary effects in capacitor dielectrics and structures affect the onset and progression of electrical breakdown and associated degradation and ageing. The work will open entirely new methods of characterizing critical pre-breakdown phenomena in complex polycrystalline solids and their internal and external interfaces, for example probing how the various physical, chemical and surface morphological mechanisms affect space charge injection, motion, and trapping, while at the same time how they affect defect motion and accumulation, and ultimately how these issues interact with dielectric polarization. The extreme multi-disciplinary nature of the results and linked understanding of the underlying science will be highly novel.
