Space Charge Modulated Electrical Breakdown. [PDF]
Sci Rep, 2016 AbstractElectrical breakdown is one of the most important physical phenomena in electrical and electronic engineering. Since the early 20thcentury, many theories and models of electrical breakdown have been proposed, but the origin of one key issue, that the explanation for dc breakdown strength being twice or higher than ac breakdown strength in ...

Electrical Breakdown of Excitonic Insulators
Physical Review X, 2023 We propose a new electrical breakdown mechanism for exciton insulators in the BCS limit, which differs fundamentally from the Zener breakdown mechanism observed in traditional band insulators. Our new mechanism results from the instability of the many-body ground state for exciton condensation, caused by the strong competition between the polarization ...

Statistical Analysis of Mechanical Strength and Dielectric Breakdown of Polyester Nano-Alumina Composites [PDF]
Journal of Applied Sciences and Nanotechnology, 2023 The mechanical and electrical properties relation are very important, especially for brittle material. Nano Alumina-unsaturated polyester (PS/Al2O3) composites were prepared by casting PS with different percentages (1, 2, 3, and 4 wt%) of Nano alumina ...

Electrical tree modelling in dielectric polymers using a phase-field regularized cohesive zone model
Materials & Design, 2023 Electrical treeing is a leading cause to the eventual breakdown of dielectric polymers under high voltages. This paper presents a simulation scheme developed based on the phase-field regularized cohesive zone model (PF-CZM) for electrical tree modelling.

Electrical breakdown in tissue electroporation [PDF]
Biochemical and Biophysical Research Communications, 2015 Electroporation, the permeabilization of the cell membrane by brief, high electric fields, has become an important technology in medicine for diverse application ranging from gene transfection to tissue ablation. There is ample anecdotal evidence that the clinical application of electroporation is often associated with loud sounds and extremely high ...
