Abstract: We demonstrate the superior performance of thin-film transistors with a functionalized single-walled carbon-nanotube-blended poly(3-hexylthiophene) (F-SWCNT-P3HT) channel and multiwalled CNT source and drain electrodes (MWCNT S/Ds). Compared with transistors with a P3HT channel and gold electrodes, the mobility of transistors with an F-SWCNT-P3HT channel and MWCNT S/Ds is increased by more than one order of magnitude, i.e., from 0.0052 to 0.072 cm(2)/V . s. This improvement results not only from the well-known fast carrier transport assisted by the blend of F-SWCNTs but also, more importantly, from the reduced contact resistance between P3HT and MWCNT S/Ds.
