Investigation of structural morphology and electrical properties of graphene-C60 hybrids
Abstract
In this work, the authors report on the electrophoretic deposition of C60 on graphene. The graphene films were characterized using Raman spectroscopy and scanning electron microscopy, and electrical contacts were made with the graphene nanomembranes using a viscoelastic stamping method. Different concentration solutions of C60 were prepared and deposited on graphene substrates using the electrophoretic deposition technique. Electronic characterization of the structures was conducted before and after the attachment of C60. Optical absorption of different concentrations of C60 was measured. A comparative study was carried out to analyze the resistivity and conductivity as a result of the interaction with a Si/SiO2 substrate. Our results suggest that graphene based C60 structures are attractive as flexible transparent electrodes and are excellent electron accepting/charge transport materials for the construction of efficient photovoltaic devices.
