Zener tunneling in conductive graphite/epoxy composites: Dielectric breakdown aspects

eXPRESS Polymer Letters, 2013
The electrical responses of conductive graphite/epoxy composites subjected to an applied electric field were investigated. The results showed that reversible dielectric breakdown can easily occur inside the composites even under low macroscopic field ...

Electric generation of vortices in an exciton-polariton superfluid

, 2012
We have theoretically demonstrated the on demand electric generation of vortices in an exciton-polariton superfluid. Electric pulses applied to a horseshoe-shaped metallic mesa, deposited on top of the microcavity, generate a non-cylindrically symmetric ...

AC breakdown characteristics of nitrogen/ oxygen gas mixtures under different electric field uniformity

AIP Advances
N2/O2 gas mixtures are the zero-GWP, low-cost, and readily available alternative to SF6. To investigate the impact of different electric field uniformity, O2 content, and gas pressure on the power frequency breakdown characteristics, this study carried ...

Breakdown Characteristics of Unequal Sphere–Sphere Electrode Configuration Under DC Stress

Engineering Proceedings
Failure of air gap insulation is one of the prominent issues in insulation coordination for outdoor applications. Though uniform electric field distribution is desirable, the difficulty in achieving it often makes insulation engineers settle for weakly ...
