Abstract

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 C₆₀ wires through the π-π interaction between rGO and C₆₀. Structural characterization of the rGO/C₆₀ wires was carried out by using UV/visible spectroscopy, scanning electron microscopy, and transmission electron microscopy. FET devices with rGO/C₆₀ wires were fabricated to investigate their electrical properties. The I _ds-V_g curves 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 C₆₀ wires 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.
