Ambipolar Transport Behaviors in Fullerene Peapod Transistors
The electrical transport properties of C70 and C60 fullerene peapods are investigated. We report the fabrications and performances of field-effect transistors (FETs) based on C70 and C60 fullerene peapods. A large percentage of the fullerene peapod-FETs we fabricated exhibit ambipolar characteristics with high Ion/Ioff ratio at room temperature in air. The origin of ambipolar behavior is qualitatively discussed.
