Space-charge dispersive transport in corona-charged dielectrics

摘要

Summary form only given. The authors suggest a model ofnspace-charge dispersive transport in noncrystalline dielectrics undernthe condition of continuous surface carrier injection (corona charging).nThey consider a sample under open-circuit conditions with rear electrodengrounded. Dispersive transport of injected space charge is describednwithin the framework of the carrier multiple-trapping model with thenPoisson equation being taken into consideration. Approximate analyticalnand numerical solutions of the equation for the dimensionless electricnfield have been obtained. Using these solutions one may calculatentime-dependent spatial distributions of the field and space-chargendensity, and time dependences of voltage and carrier packet meannposition
