Field-effect transistor with a conducting polymer film

Abstract Spin-coated conducting polymer films of poly(3-hexylthiophene) (PHT) and poly(2,5-thienylene vinylene) (PTV) have been demonstrated to be useful in a field-effect transistor (FET) as a semiconducting layer. The device with a doped PHT film shows enhance-type FET characteristics although they are unstable. On the other hand, the one with a non-doped PTV film shows very stable and excellent FET characteristics with large source current.
