Abstract(in English) | In this study, we have investigated the FET properties and the dielectric properties of Poly(3-hexylthiophene)(P3HT) FET prepared on Ta_2O_5/polyimide double layered gate insulator. We succeeded to reduce the effective thickness of gate insulator by the use of double layered structure consisting of ultra thin polyimide (~30nm) and the high-K dielectric Ta_2O_5 layers. The threshold voltage changed positively by inserting polyimide thin film and this change was attributed to the displacement of electrons from P3HT to electron accepting polyimide films. We have observed the dielectric dispersion based on Maxwell-Wagner model and the interfacial layers of a few nm at the semiconductor/gate insulator interface. It is proved that the interfacial layer exercise an influence on FET properties. |
