Abstract :
To further clarify the carrier behavior of polytetrafluoroethylene (PTFE), the authors studied the nonlinear conduction properties of PTFE film of 50-μm thickness at temperatures between 20°C and 40°C and with a field intensity between 10 and 400 MV/m. The observed nonlinear conduction properties of the PTFE films varied with the temperature and the electric field and can be explained in terms of conduction phenomena that can be divided into four different regions showing ohmic, Poole-Frenkel, Schottky, and Fowler-Nordheim effects, respectively
