By a simple helium arc-discharged method, we explored the suitable conditions for producing graphene sheets by regulating gas pressures and currents. Graphene sheets containing monolayer, bilayer and few layers were obtained. The as-obtained graphene sheets were verified by transmission electron microscopy (TEM), electron diffraction and scanning electron microscopy (SEM). (C) 2009 Elsevier B.V. All rights reserved.
