| Abstract(in English) | Top contact organic field-effect transistors (OFETs) based on a composite of α, ω-dihexylsexithiophene (DH-6T) using poly (3-hexylthiophene) (PAT6) with the same thiophene backbone were fabricated by spin coating using an annealing solution of PAT6 and DH-6T. The size of grains with a sphere like morphology increased with the mass percentage of DH-6T in the composite. In the case of a DH-6T composite of more than 80 weight (wt)%, the field-effect mobility of the OFET rapidly increased. An OFET with an 89 wt% DH-6T composite corresponding to two molecules of DH-6T per hexylthiophene repeating unit had a carrier mobility of 0.028 cm^2/Vs. The different morphologies of the OFETs with non-OTS treated and OTS-treated gate insulators result in the improvement of field-effect mobility. We demonstrated that it is possible to achieve high field-effect mobility and a high on/off ratio of the OFET using soluble DH-6T with PAT6 composites fabricated by spin coating. |
