Abstract
The TSC (thermally stimulated current) spectra of a semicrystalline PET (polyethylene tetrafluoride) film has been investigated. The TSC spectra shows two peaks: a peak whose temperature is ≈105°C, and a negative resistivity peak at ≈140°C. The origin of homocharging is discussed. Four electron spectra are presented. It demonstrated that acetate remained at the surface of the PET film. The catalysts of the ion disappeared as a result of heat treatment. Hence, the negative peak of TSC in PET is associated with the surface ion impurity
