Mobility enhancement of P3HT-based OTFTs upon blending with Au nanorods
The mobility enhancement of organic thinâfilm transistors based on poly(3âhexylthiophene) (P3HT) by incorporating gold nanorods (Au NRs) is reported. Through varying the doping concentration and surface modifier of the Au NRs in P3HT matrix, the P3HT/Au composite with 0.5 mg mLâ1 pyridineâcapped Au NRs exhibits a hole mobility of 0.059 cm2 Vâ1 sâ1, this value is seven times higher than that of pristine P3HT. This remarkable improvement of mobility originates from the enhanced crystallinity and optimized orientation of P3HT after doping with Au NRs. In addition, the appropriate surface modification can produce moreâefficient hole conduction of Au NRs
