Simultaneous measurement of electroluminescence and space charge distribution in low-density polyethylene under DC field

摘要

We report for the first time the simultaneous measurement of the electroluminescence and the space charge distribution in cross linked polyethylene under high DC field using a specially-developed pulsed electro-acoustic apparatus. An interpretation of the observed behaviour is proposed with the help of a numerical model of transport including the effect of charge trapping and recombination.
