Simulation of space charge behavior in LDPE with a modified of bipolar charge transport model

Proceedings of 2014 International Symposium on Electrical Insulating Materials, 2014
In this paper, an simply ion charge transport model is proposed, compared with bipolar charge transport model. It consists of ion generation by field assisted dissociation of impurities, transport, trapping and recombination in polymer. To simplify the model, it is assumed that only one type of impurity existing in polymer.

Simulation of bipolar charge transport in graphene on h-BN

COMPEL - the International Journal for Computation and Mathematics in Electrical and Electronic Engineering, 2020
Purpose The purpose of this paper is to simulate charge transport in monolayer graphene on a substrate made of hexagonal boron nitride (h-BN). This choice is motivated by the fact that h-BN is one of the most promising substrates on account of the reduced degradation of the velocity due to the remote impurities.

Bipolar resistive switching and charge transport in silicon oxide memristor

Materials Science and Engineering B: Solid-State Materials for Advanced Technology, 2015
Abstract Reproducible bipolar resistive switching has been studied in SiO x -based thin-film memristor structures deposited by magnetron sputtering technique on the TiN/Ti metalized SiO 2 /Si substrates. It is established that, after electroforming, the structure can be switched between the quasi-ohmic low-resistance state related to silicon chains

Charge transport properties of insulators revealed by surface potential decay experiment and bipolar charge transport model with genetic algorithm

IEEE Transactions on Dielectrics and Electrical Insulation, 2012
To evaluate spacecraft charging level and predict surface and internal electrostatic discharging (ESD) probability, it is important to know the charge transport properties of high insulation materials, such as epoxy resin/glass composition (FR4), Teflon and polyimide. In present work, the charge transport properties of the space insulators are revealed

Roughness Enhanced Charge Injection and Field Dependent Conduction Mechanisms for Bipolar Charge Transport Models

2020 IEEE 3rd International Conference on Dielectrics (ICD), 2020
Extruded HVDC cable systems contain a multitude of different interface types. Physical interfaces are introduced on-site when the outer semi-conductive layer is removed prior to installing a pre-molded joint or stress-cone onto the cable end. Such interfaces are characterized by surface roughness, which can locally enhance electric field and stimulate ...

Bipolar Charge Transport in PCPDTBT‐PCBM Bulk‐Heterojunctions for Photovoltaic Applications

Advanced Functional Materials, 2008
AbstractAn experimental study of the transport properties of a low‐bandgap conjugated polymer giving high photovoltaic quantum efficiencies in the near infrared spectral region (Eg‐opt ∼ 1.35 eV) is presented. Using a organic thin film transistor geometry, we demonstrate a relatively high in‐plane hole mobility, up to 1.5 · × 10−2 cm2 V−1 s−1 and ...

A New Approach for Optimizing a Bipolar Charge Transport Model for Dielectric Materials: Theoretical Framework

IEEE Transactions on Dielectrics and Electrical Insulation, 2021
International audienceA bipolar charge transport model with two levels of traps (shallow and deep traps) is employed to describe and investigate the dynamic behavior of the space charge in low-density polyethylene (LDPE). This kind of model requires some

Modelling of Electroluminescence in Polymers Using a Bipolar Charge Transport Model [PDF]

, 2011
Electroluminescence (EL) in polymeric materials is thought to occur due to the energy dissipation process from the recombination of opposite polarity charge carriers. It is considered as an indication of storage and transport of charge carriers in cable insulation subject to electrical stresses and may indicate the change in charge movement due to ...

Bipolar Hydrodynamical Model for Charge Transport in Graphene Nanoribbons

Journal of Computational and Theoretical Transport, 2022
A hydrodynamical model for charge transport in narrow strips of graphene is here presented. The model takes into account the interactions with the well-known lattice vibrations and with the edge of the strip. The remarkable result is the modulation of the charge current due to the swapping of charge carriers between the conduction and the valence bands,
