Notes:
When FEP-Teflon samples are electron irradiated at room temperature in open circuit and stored in that state for varying times following the end of irradiation, the temperature of the first current peak of the short-circuit TSC plot increases with increasing storage time. A new model is presented to explain this phenomenon, its main features being (i) a quasicontinuous distribution of hole-trap activation energies, the “center of mass” of the trapped hole population moving toward the deeper end of the distribution during the storage time, and (ii) an electron/hole recombination coefficient much smaller than that implied in an earlier model. It is shown that the assumption of a single dominant type of hole trap implies an unrealistically large frequency factor.
