Field-induced breakdown of the quantum Hall effect

, 1999
A numerical analysis is made of the breakdown of the quantum Hall effect caused by the Hall electric field in competition with disorder. It turns out that in the regime of dense impurities, in particular, the number of localized states decreases ...

Mechanical and Microstructural Effects of ZrO2 Nanoparticles in Fe20Cr Oxide Dispersion‐Strengthened Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
The influence of oxide nanoparticle synthesis route and concentration on microstructure and high‐temperature performance of additively manufactured oxide dispersion‐strengthened steels is investigated. Comparing laser‐generated and chemically synthesized ZrO2 nanoparticles, the study reveals how dispersion quality, crystal structure and particle size ...

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 ...

Effect of moisture on the electric field and breakdown voltage of XLPE cable interconnectors

AIP Advances
Dampness in the joint is a common defect of power cables, and the influence of moisture on the performance of the intermediate joint is very important. The electric field distribution of the joint is analyzed by simulation, and the XLPE sample is used as

Layer-by-Layer Dielectric Breakdown of Hexagonal Boron Nitride [PDF]

ACS nano, 2015, 9, 916, 2015
Hexagonal boron nitride (BN) is widely used as a substrate and gate insulator for two-dimensional (2D) electronic devices. The studies on insulating properties and electrical reliability of BN itself, however, are quite limited. Here, we report a systematic investigation of the dielectric breakdown characteristics of BN using conductive atomic force ...

Breakdown Current Density of Graphene Nano Ribbons [PDF]

, 2009
Graphene nanoribbons (GNRs) with widths down to 16 nm have been characterized for their current-carrying capacity. It is found that GNRs exhibit an impressive breakdown current density, on the order of 10^8 A/cm2. The breakdown current density is found to have a reciprocal relationship to GNR resistivity and the data fit points to Joule heating as the ...

Quantum Response at Finite Fields and Breakdown of Chern Numbers

, 1999
We show that the response to an electric field, in models of the Integral Quantum Hall effect, is analytic in the field and has isolated essential singularity at zero field.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior

Advanced Engineering Materials, EarlyView.
Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...
