The assembly of reduced graphene oxide (rGO) and fullerene (C60) into hybrid (rGO/C60) wires was successfully performed by employing the liquid–liquid interfacial precipitation method. The rGO sheets spontaneously wrapped C60wires through the π–π interaction between rGO and C60. Structural characterization of the rGO/C60wires was carried out by using UV/visible spectroscopy, scanning electron microscopy, and transmission electron microscopy. FET devices with rGO/C60wires were fabricated to investigate their electrical properties. The Ids–Vgcurves of the hybrid wires exhibited p-type semiconducting behavior both in vacuum and in air, indicating hole transport through rGO as a shell layer, whereas pure C60wires and rGO sheets showed n-type and ambipolar behaviors, respectively, under vacuum. Possible application of the fabricated wires, such as photovoltaic devices, was also demonstrated. |
