| Abstract: | The fabrication of air-stable ambipolar organic field-effect transistors with sandwich-type and bilayer architecture based on copper phthalocyanine and 7,7,8,8-tetracyanoquin odimethane is reported. In comparison with bilayer devices, the sandwich-type configuration enhances the performance and reproducibility of ambipolar devices, which is mainly ascribed to the double conductive channels in the sandwich-type structure. The measured p-channel and n-channel mobility of sandwich-type devices are comparable to that of copper phthalocyanine and 7,7,8,8-tetracyanoquinodimethane single layer devices, respectively. |
