▎ 摘　　要

NOVELTY - Method for forming a graphene film, involves (a) depositing a non-gaseous carbon source on a catalyst surface, and (b) initiating the conversion of the non-gaseous carbon source to graphene film on the catalyst surface. USE - The method is useful for forming graphene film (claimed) used for optoelectronics. ADVANTAGE - The formed film has desired thickness, size, pattern, electrical properties, low defects, low sheet resistance, ambipolar field effects, low temperature growth, patterened growth, large area growth and easy transferabiltiy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene film, which is obtained by the above-cited method.
