David J. Gundlach, James Royer, Behrang Hamadani, Lucile C. Teague, Andrew J. Moad, Oana Jurchescu, Oleg A. Kirillov, Lee J. Richter, James G. Kushmerick, Curt A. Richter, Sungkyu Park, Thomas Jackson, Sankar Subramanian, John E. Anthony
Organic electronics present a tremendous opportunity to significantly impact the functionality and pervasiveness of large-area electronics. However, the lack of low-temperature low-cost deposition and patterning techniques limits the potential for the

Undoped polythiophene FETs with field-effect mobility of 1 cm^2 V^-1 s^-1

Behrang Hamadani, Iain McCulloch, Martin Heeney, David J. Gundlach
We report on charge transport in organic field-effect transistors based on (2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) as the active polymer layer with saturation field-effect mobilities as large as 1 cm2 V-1 s-1. The dependence of mobility

Distinguishing Between Nonlinear Channel Transport and Contact Effects in Organic FETs

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
