Popis:	Thermally stimulated currents and “scanning temperature conduction currents” are studied in FEP thin films with ion plated aluminum electrodes (Al*). In these films, a rapid increase in the positive charge flow I p from the interfacial region between Al* and FEP into the bulk of FEP is observed at elevated temperatures. This rapid increase in I p begins at lower temperatures as the accelerating voltage V a for the ion plating increases. In negatively corona-charged FEP films with Al*, three TSC peaks appear depending on V a. The highest-temperature peak of the three is the extrinsic one originating from neutralization of the trapped charges by I p. The annealed samples show only the extrinsic TSC because of the low thermal stability of the trap sites which are responsible for the intrinsic TSCs.
