Space Charge Modulated Electrical Breakdown. [PDF]

open access: yesSci 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 ...

Degradation patterns of silicone-based dielectric elastomers in electrical fields [PDF]

open access: yesInternational Journal of Smart and Nano Materials, 2018
Silicone elastomers have been heavily investigated as candidates for the flexible insulator material in dielectric elastomer transducers and are as such almost ideal candidates because of their inherent softness and compliance.

Electrical polarization of nuclear spins in a breakdown regime of quantum Hall effect [PDF]

open access: green, 2006
We have developed a method for electrical polarization of nuclear spins in quantum Hall systems. In a breakdown regime of odd-integer quantum Hall effect (QHE), excitation of electrons to the upper Landau subband with opposite spin polarity dynamically ...

Electrical breakdown of carbon nanotube devices and the predictability of breakdown position [PDF]

open access: goldAIP Advances, 2012
We have investigated electrical transport properties of long (>10 μm) multiwalled carbon nanotubes (NTs) by dividing individuals into several segments of identical length. Each segment has different resistance because of the random distribution of defect

Synergistic improved electrical resistivity-temperature characteristics and DC breakdown strength in insulating XLPE composites by incorporating positive temperature coefficient particles

open access: yesPolymer Testing, 2023
Weakening the electrical resistivity-temperature dependence of cross-linked polyethene (XLPE) is an effective way to enhance the electric field uniformity of high-voltage direct current (HVDC) cables.

Statistical Analysis of Mechanical Strength and Dielectric Breakdown of Polyester Nano-Alumina Composites [PDF]

open access: yesJournal 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 ...
