The charge Carrier Trap Energy Levels of Two Different Polyimide Films Characterized by Three Methods
The charge carrier trap energy level is an important parameter that will affect the electrical and optical properties of insulating and semiconducting materials. Depending on the characterizing methods, it has a remarkable difference. The trap energy levels of two kinds of polyimide films, original (100HN) and corona-resistant (100CR) ones produced by Dupont, are estimated by depolarization current, space charge limited current and thermally stimulated current method. The corresponding values are 1.185eV-1.200eV and 1.168eV-1.220eV, 0.93eV and 0.76eV, 0.65-0.91eV and 0.60-0.90eV, respectively. These results show that the trap energy level of polymers comes significantly under the influence of heating procedures, and the shallower traps are constructed in corona-resistant polyimide film.
