    Abstract: Open-circuit thermally stimulated discharge currents in polyethylene 
  terephthalate films have been investigation in the poling temperature range 
  of 30-150°C. This material shows a negative TSDC intensity peak at approximately 
  80°C originated from dipolar process and another around 110°C (ρ-peak) 
  attributed to the manifestation of space-charge effects. Since, this polymer 
  is a commercially available and well known material, the main focus is set on 
  the thermo-electrical properties. Therefore, the dependence of the polarization 
  on the poling temperature has been utilized to look at the polarization which 
  has been stored during the poling process. These measurements show an upper 
  limit for the polarization.
