| Popis: | We demonstrate ambipolar charge transport in organic field-effect transistors based on the solution processible methanofullerene [6,6]-phenyl-C-71-butyric acid methyl ester ([70]PCBM). The electron mobility measured in the linear and saturated regimes is approximately equal and of the order of 1 X 10(-3) cm(2)/V s. In the linear regime, mobility is thermally activated with a strong gate bias dependence. The p-channel hole mobility is lower with a maximum value of 2 X 10(-5) cm(2)/V s. The n- and p-channel operations are characterized by a low (similar to vertical bar 3 vertical bar V) and a high (similar to vertical bar 50 vertical bar V) switch-on voltage, respectively, with the on-off current ratio on the order of 10(4) for both channels. Although the present findings are qualitatively similar to those reported previously for C-60-methanofullerene-based transistors, [70]PCBM devices are more stable and easier to reproduce. By making use of this property we are able to demonstrate functional unipolar and complementarylike logic circuits with promising operating characteristics. |
