紀要論文 絶縁性高分子の界面準位の評価法

川本, 昂

内容記述
In a composite of PMMA (polymethyl-methacrylate) and PS (polystyrene), electrons transportedfrom the PMMA layer can pass through the interface more easily than holes from the PMMA layer.Holes from the PS layer can pass through the interface more easily than electrons from the PSlayer. As exemplified electrons from the PS layer. As exemplified above, the charge-exchange rate at the interface in insulating composites is affected by the direction of the carrier transport. Such asymmetric characteristics are widely seen in insulating composites e.g. PE-EVA and epoxy alumina and seem very important to understand the insulation performance of composites1. 2) .In order to clarify the asymmetric properties on the basis of electronic levels, it is necessaryto establish the methods for estimating electronic levels in polymers. In this paper, electronic levels in insulating polymers were estimated by contact potential difference, XPS, UPS in air and photoinjection current and the correlation among the estimated levels was investigated.
