An organic field-effect transistor based on a copper-phthalocyanine and cyanoethylpullulan gate insulator showed ambipolar operation using gate insulator hysteresis, which appeared at less than 1 mHz. The gate insulator possesses spontaneous polarization of 1.6 μC/cm2 and a coercive electric field of 50 kV/cm. After poling in an effort to obtain a large amount of accumulated charge, the field-effect mobilities of the hole and electron were 4.1×10-3 and 3.5×10-6 cm2/Vs, respectively. The on/off ratio at VSG=±10 V was 6×104 for the p type and 70 for the n type.

    Recent research has revealed that the overall effective mobility of organic field-effect transistors depends on the anisotropy film. To account for this behavior, a modified model is proposed based on the previous grain boundary trap model. In this model, the degeneration factor, which is...

    We investigate the possibility to maintain an electric polarization in an organic bilayer via ion trapping, i.e., without any external bias. In the cryptand-polyanion bilayer, ions of specific size can be strongly coordinated with organic macrocyclic molecules. Cations move from the polyanion...
