  • Increased mobility from organic semiconducting polymers field-effect transistors
    Publication number: 20060128053
    Abstract: Organic FETs are produced having high mobilities in the accumulation mode and in the depletion mode. Significantly higher mobility is obtained from FETs in which RR-P3HT film is applied by dip-coating to a thickness of only about 20 ? to 1 ?m. It was found that the structural order of the semiconducting polymer at the interface between the semiconducting polymer and the SiO2 gate-insulator is important for achieving high carrier mobility. Heat-treatment under an inert atmosphere also was found to increase the on/off ratio of the FET.
