| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The fabrication and electrical and optical properties of top-gate-type organic field effect transistors (OFETs) utilizing poly(9,9dioctylfluorenyl-2,7-diyl) (F8) were investigated. The OFETs utilizing F8 showed ambipolar characteristics and blue emission. Then, the Ag nano-ink was used for the gate electrode to fabricate OFETs only in the solution-process. The amorphous fluoro-polymer Cytop (Asahi Glass Co., Ltd.) which has good solution barrier properties was used for the gate insulator and the UV light was irradiated on Cytop film in the mixture atmosphere of nitrogen and oxygen to decrease water-shedding quality of the film. As a result, the surface energy of Cytop was increased by UV irradiation, and the gate electrode was fabricated in solution-process on the Cytop film by using the Ag nano-ink. However, after irradiated UV light, the photo-degradation of F8 was observed. Consequently, the saturation current of OFETs in the electron enhancement mode markedly decreased, and the EL emission was not observed. It is suggested that the oxygen bindings were generated to F8 film by UV irradiation, and acted as an electron trap sites. | |
