• The Thermally Stimulated Depolarization Current method allowed us to emphasize the role played by aluminum-polyester contacts on the electrical properties of Metal-Polyethylene Terephthalate films-Metal systems. Assuming the existence of Schottky barriers at the Al-PET interfaces after heat treatment, the electronic band model permitted us to account for the nature and properties of the space charge in annealed PET films (1.5 to 12 /spl mu/m), in a wide range of poling temperatures, times and fields.
