NOVELTY - Chemical doping of graphene film involves irradiating laser to graphene film immersed in melt containing metallic compound dissolved in solvent. USE - Chemical doping of graphene film. ADVANTAGE - The method produces pure graphene film with reduced resistivity and high crystallinity. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of manufacturing apparatus of graphene film. Reaction container (1) Waveguide (2) Plasma excitation board (3) Slot antenna (4) Manufacturing apparatus (100)
