摘要: We investigate a dual layer active channel of random distributed intrinsic silicon nanowires and solution processing semiconducting polythiophene polymers for organic-based field 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 nanowire-polythiophene devices is found to be more sustainable with respect to that of pristine polythiophene in ambient air. These results indicate that semiconducting nanowires should be considered as a viable additive to active channel for next-generation organic field effect transistors. (C) 2016 Elsevier B.V.
