RESUMO

The Heat Pulse and TSC (Thermo-Stimulated-Current) in open circuit techniques were used to study the transport and storage of injected charge in Teflon FEP films. Using these techniques it was possible to follow the evolution of the injected charge inside the samples. Virgin samples (as received), previously annealed samples and previously ionic bombarded samples were used. The results of treated samples were compared with the results of virgin samples. Aluminum evaporate contacts covering ionic bombarded surface show hole injection properties. Measurement of space charge limited currents shows a mobility dependent of the electrical field (μ α E-1/2).
