Friction transfer deposition of ordered conjugated polymer nanowires and transistor fabrication

Abstract

Monodisperse, ordered conjugated polymer nanowires were deposited by friction-transfer technique. Films that comprise such ordered polymer nanowires show a strong optical and electronic anisotropy due to the high compaction of molecule chains in the individual nanowires. Field-effect transistors that were fabricated using poly[9,9-dioctylfluorene-co-bithiophene(F8T2)] nanowires exhibit a field-effect mobility of 3.5×10−2cm2V−1s−1 along the wire direction, which is much higher than the mobility value (5×10−3cm2V−1s−1) obtained in transistors with spin-coated F8T2.
