Electronic charge exchange at insulator-insulator interface in insulating composites

Proceedings of 1994 4th International Conference on Properties and Applications of Dielectric Materials (ICPADM), 2002
The charge exchange at the insulator-insulator interface in insulating composites is affected by the direction of the carrier transport and carrier species. In this paper the charge exchange process at the PS-PMMA interface was discussed on the basis of asymmetric photoconduction and contact charging.
