    Abstract

    Through measuements of high-field conduction and space-charge formation in high-density polyethylene film with and without the surface layer of plasma polymerized ethylene, the following points have been clarified: (1) the TPC measurements show that electrons and holes are injected into high-density polyethylene at fields above 0.2 MV/cm and 0.8 MV/cm, respectively. (2) high-field conduction in high-density polyethylene is due mainly to space-charge-limited current by electrons. (3) plasma-polymerized ethylene is amorphous with many localized states in the forbidden band and traps the injected electrons and holes. As a result, when deposited as a surface layer, it suppresses the succeeding carrier injection from the electrode.
