NOVELTY - Growth method of multilayer graphene single crystal film involves placing copper foil in hydrogen atmosphere, heating and annealing, maintaining constant temperature in copper foil, continuously filling mixed gas of hydrogen gas, methane and argon gas, and continuously filling mixed gas of hydrogen gas, methane and argon gas under copper foil. USE - The method is used for growing multilayer graphene single crystal film. ADVANTAGE - The method has high controllability, and controls graphene growth and number and size of graphene grown on upper side of copper foil substrate. The film has large size and high quality.
