| Abstract: | Thin (25  m) foils of Teflon® FEP are charged positively in a constant-current corona triode with currents between 1–6×10–9 A to a voltage of 3 kV. Experimental results give the voltage as a function of time during charging and during the discharge which occurs after the corona current has been turned off. Results can be interpreted in terms of a theory which introduces shallow surface and deep bulk traps and assumes that the field-induced carrier drift is characterized by a constant schubweg. |
