Few layered graphene sheets were synthesized by the electric arc method by sublimation of graphite in helium used as a buffer gas. The arc was created between two graphite electrodes subjected to a continuous electric current. Experiments were designed and conducted by careful control of the turbulent flow leaving radially from a very small inter-electrode space. The graphene obtained was characterized by Raman spectroscopy and by X-ray diffraction.
