High-mobility field-effect transistors fabricated with macroscopic aligned semiconducting polymers

Abstract

A record high OFET hole mobility, as high as 23.7 cm2/Vs, is achieved in macroscopic aligned semiconducting polymers. The high mobility is insensitive to the polymer molecular weight. Polymer chains are aligned along the fiber to facilitate intrachain charge transport. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
