제목 The electrical reliability of organic field-effect transistors with various polymer dielectrics
초록 The electrical reliability of organic field-effect transistors (OFETs) is critical issue for the long-term operation and their commercialization. We can demonstrate that the electrical properties of OFETs by bias stress. In case of OFETs, recent studies have demonstrated that charge trapping is occurred in the semiconductor and gate dielectric interface. Also, they report that most of the trapped charges are in gate dielectric not in semiconductor. In this study, the bias stress stabilities of OFETs with various polymer gate dielectrics are investigated in order to demonstrate effect of polymer characteristics. Under bias stress, the drain current decay and the threshold voltage shift are found to different as polymer characteristics without changes mobilities of OFETs.
