▎ 摘 要
NOVELTY - Manufacturing graphene comprises growing graphene on the single-crystal metal foil by supplying a gaseous carbon source to the single-crystal metal foil according to the condition as given in the specification. USE - The single-layer single-crystal graphene is useful in devices and laminate (all claimed). ADVANTAGE - The single-layer single-crystal graphene: is free from folding defects, grain boundaries, wrinkles and adlayers; does not substantially show the D-band peak on the Raman spectrum; is produced on a single crystal metal foil and prevents step bunching. The method: produces large-area high-quality graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: ingle crystal graphene comprising single layer with a large area of /-25 cm2 and free from folding defects; and laminate comprising single-layer single-crystal graphene and a substrate supporting the single-layer single-crystal graphene.
