▎ 摘　　要

NOVELTY - Synthesis of graphene involves placing a copper-nickel thin film laminate comprising a copper thin film and a nickel thin film placed on the copper thin film in a chemical vapor deposition, bringing a graphene precursor into contact with the laminate and performing the chemical vapor deposition. USE - Synthesis of graphene for optoelectronic devices. ADVANTAGE - The process produces graphene with improved uniformity and electroconductivity, and controlled thickness and number of layers with simple process parameters. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a patterned graphene comprising a graphene portion (A) comprising m graphene layers, and a graphene portion (B) connected side by side to the portion (A) through covalent bonding and comprising m+n graphene layers, where m and n are 1-5.
