Abstract

The anisotropy of the charge carrier mobility in stretch oriented thin films of undoped poly(3-octylthiophene) has been investigated. The mobility has been measured using a field effect transistor onto which the polymer film is coated. The anisotropy increases with increasing orientation, reaching values of 4. Causes of this anisotropy, including residual dopant distributions, conjugation length anisotropy, intrinsic anisotropy of transport on and between chains, as well as crystallinity and monodisperse conjugation lengths are discussed.
