Abstract
In this paper, we explore ambipolar organic field-effect transistor (FET) characteristics using bilayer, binary blends, and paralleled nanofibers of poly(3-hexylthiophene) (P3HT; p-type) and poly{[N,N′-bis(2- decyltetradecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl] -alt-(thiophene-2,5-diyl)} (P(NDI-T); n-type). Ambipolar transistors with paralleled single P3HT and P(NDI-T) electrospun nanofibers showed high and well-balanced mobilities of 8.25 × 10-2 cm2 V -1 s-1 for holes and 7.51 × 10-2 cm 2 V-1 s-1 for electrons with I on/Ioff ≈ 104. This ambipolar nanofiber FET was also applied to a complementary inverter with a gain of up to 20.5. © the Partner Organisations 2014.
