英文摘要	We present an investigation on the carbon scrolls produced from chemical vapor deposition (CVD) grown graphene. A wet, polymer-mediated process is used to transfer CVD grown graphene from copper foil to a Si/SiO2 or metal substrate. Upon the removal of polymer and drying, tearing of the graphene occurs and carbon scrolls are produced from the ruptured graphene. We demonstrate that the optical and electronic properties of these scrolls are comparable to those from exfoliated graphene. Optical microscopy and scanning electron microscopy show that the isolated scrolls exhibit a similar morphology to those formed from exfoliated graphene. Raman spectroscopy has been used to investigate the conformational change from graphene to scrolls. The scrolls have a more pronounced Raman D peak than graphene and display a large variation in the integrated intensity of Raman G and G' peaks at different scroll locations. Raman spectroscopy and transmission electron microscopy confirm that the graphene layers in the scrolls are non-AB stacked. The scroll field-effect-transistor (PET) device exhibits an ambipolar behavior, resembling the graphene FET device. This work demonstrates the possibility of fabricating carbon scrolls using CVD grown graphene on various substrates and paves the way for advancing their applications. (C) 2014 Elsevier Ltd.
