A model for bipolar charge transport, trapping and recombination in degassed crosslinked polyethene

Journal of Physics D: Applied Physics, 1994
Measurements of the space charge density across the width of a plane parallel sample of degassed crosslinked polyethene (XLPE) have been made recently. Repeated at intervals throughout a period of applied high voltage, these measurements provide data on the dynamics of charge injection and space charge development in the sample under the influence of a

A unified analytical model for charge transport in Heterojunction Bipolar Transistors

Solid-State Electronics, 2004
Abstract A unified analytical charge transport model of HBTs, which is applicable for a wide variety of emitter-base (e–b) structures of HBTs, viz. abrupt or graded heterojunctions and p–n junctions displaced into wider or narrower band gap material is proposed.

Simulation of low-energy electron beam irradiated PTFE based on bipolar charge transport model

IEEE Transactions on Dielectrics and Electrical Insulation, 2016
Studies on charge transport properties of space grade insulating materials become popular recently because it is closely related to the safe operation of spacecraft. Taking charge carriers retrapping and hole injection into consideration, we simulated the surface charging and the space charge accumulation properties of PTFE under lowenergy electron ...

Bipolar Charge Transport Model with Trapping and Recombination: An Analyze of the Current vs. Applied Electric Field Characteristic

2007 IEEE International Conference on Solid Dielectrics, 2007
A bipolar model of transport intended to describe the behaviour of polyethylene in steady state is presented. The model is based on Poisson's equation and the conservation law of charges, trapping, detrapping and recombination phenomena being taken into account.

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,

A model for bipolar charge transport in insulators

Proceedings of 1995 IEEE 5th International Conference on Conduction and Breakdown in Solid Dielectrics, 2002
Failure of electrical cable insulation is still a major problem for the electricity generation and supply industries. Under high field conditions (>10/sup 8/ Vm/sup -1/), space charge and the concomitant electric field dynamics are involved in the initiation of dielectric breakdown.

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 ...
