Producing graphene thin film involves coating multiple different metals having different carbon solubilities on upper surface of substrate to form multilayer metal film, and injecting multiple carbon atoms on upper surface of metal film.

KIM J H

Production of graphene used as wiring material, involves supplying carbon-containing gas and metal catalyst into chamber and reactivating catalyst by supplying process gas and carbon-containing gas to regrow graphene on catalyst surface.

IFUKU R, MATSUMOTO T

Preparation of graphene film for use in e.g. display, involves mixing expanded graphite with water, mixing graphene precursor, surfactant, reducing agent and metal salt in solvent, adding sulfuric acid solution.
