Nonlinear electric conductivity and thermal conductivity of WS2/EPDM field grading materials

Journal of Applied Physics, 2017
In this work, composites with different flake-like WS2 filler contents were prepared, using ethylene propylene diene monomer as matrix. The nonlinear electric conductivity of composites at 25, 50, and 80 °C was measured, and the mechanisms were analyzed.

Electrically Switchable Longitudinal Nonlinear Conductivity in Magnetic Semiconductors

Physical Review Letters
Writing data by electric field (as opposed to electric current) offers promises for energy efficient memory devices. While this data writing scheme is enabled by the magnetoelectric effect, the narrow spectrum of room-temperature magnetoelectrics hinders the design of practical magnetoelectric memories, and the exploration of other mechanisms toward ...

Optimization of Carbon Nanotube Doping on Nonlinear Conductivity, Surface Charge Dissipation and Electric Field Regulation of SiC/SR Composites Insulators Subjected to DC High Voltages

IEEE transactions on dielectrics and electrical insulation, 2023
Adaptive material can alleviate the local high electric field in electrical devices, due to its nonlinear conductivity characteristics. To solve the deterioration problem caused by the high doping of large-diameter fillers in the adaptive material ...

Analysis of Nonlinear Conductivity Coating used to Improve Electric Field Distribution in Medium Voltage Power Module

European Conference on Cognitive Ergonomics, 2022
By establishing a finite element simulation model in COMSOL, the electric field distribution of a 15kV power module is analyzed, and the local maximum electric field is reduced by using nonlinear conductivity materials.

Nonlinear electrical conductivity in hydrogen plasma

Physics of Fluids B: Plasma Physics, 1993
Employing the Zubarev method for the derivation of a nonequilibrium statistical operator, Vlasov–Uehling–Uhlenbeck quantum kinetic equations are derived for the distribution functions of clusters with arbitrary mass number. Considering a partially ionized hydrogen plasma, the electronic distribution function is determined numerically for the ...

Nonlinear electrical conductivity in heterogeneous media

Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1997
Let a spatial domain \(V\) be divided into domains \(V_r\) \((r=1,2, \dots, N)\), and let \(f_r\) be the characteristic function of the set \(V_r\). The authors consider a composite material derived by the nonlinear equations \(\text{div} {\mathbf J} =0\), \({\mathbf J}= {\partial \over \partial {\mathbf E}} (\sum^N_{r=1} f_r({\mathbf x}) f_r ({\mathbf

Electrical Conductivity Relaxation in the Nonlinear Regime

Journal of The Electrochemical Society, 2017
Electrical Conductivity Relaxation (ECR) is an experimental procedure used to assess the chemical diffusion and reaction coefficients (i.e. D-chem and k(chem)) of mixed ionic electronic conductors (MIECs). The analytical model usually employed to fit the ECR data is based on linear physics.

Kinetic theory of nonlinear electrical conductivity

Annals of Physics, 1968
Abstract The nature of the corrections to Ohm's law in the weak field domain is investigated. Exact solutions of kinetic equations with separable collision terms are obtained. The distribution function is shown to have an essential singularity in several regions of velocity space as the applied field tends to zero.

Odd Nonlinear Conductivity under Spatial Inversion in Chiral Tellurium.

Physical Review Letters, 2023
Electrical transport in noncentrosymmetric materials departs from the well-established phenomenological Ohm's law. Instead of a linear relation between current and electric field, a nonlinear conductivity emerges along specific crystallographic ...
