We investigate a dual layer active channel of random distributed intrinsic silicon nanowires and solution
processing semiconducting polythiophene polymers for organicbased eld effect transistors. Primary
results show that low density silicon nanowire networks could enhance the effective charge carrier
mobility of polythiophene transistors by a factor of six, suggesting that these nanowires act as rapid one
dimensional charge transport bridges in the active channel. Moreover, increasing the nanowire loading
in the dual layer nanocomposite could further lessen the transistor hysteresis. The lifetime test of
nanowirepolythiophene devices is found to be more sustainable with respect to that of pristine poly
thiophene in ambient air. These results indicate that semiconducting nanowires should be considered as
a viable additive to active channel for nextgeneration organic eld effect transistors.
