We investigate charge injection and transport in organic field-effect transistors fabricated by using poly(2,5-bis(3-tetradecylthiophene-2-yl)thieno[3,2-b]thiophene) (pBTTT-C14) as the active polymer layer. We show that in high mobility devices where the

Influence of source-drain electric field on mobility and charge transport in organic field-effect transistors

August 21, 2007

Author(s)

Behrang Hamadani, R J. Kline, Iain McCulloch, Martin Heeney, Curt A. Richter, David J. Gundlach

We report on a strong field-dependent mobility in OFETs fabricated by using poly(2,5-bis(3-alkylthiophene-2-yl)thieno[3,2-b]thiophene) (pBTTT-C14) as the active polymer layer. Charge transport and mobilities in devices annealed in the mesophase show a more
