摘要

We propose a dielectric sample model to investigate the threshold field for charge injection at electrode/dielectric interfaces by space charge observation. The model sample consists of a dielectric layer and two thin charge blocking layers, respectively, placed at the inside and one side of the dielectric layer. The method has been applied to investigate the threshold field for charge injection from Al, Au, or semiconductive electrode into polyethylene. Experimental results show that charge injection occurs so long as the interface electric field is nonzero, i.e., there is no indication of a threshold field for the charge injection.
