Abstract
A maskless, patterned graphene film is produced through use of a tunable metal as a catalyst for graphene growth. The metal layer contains precisely defined textures that control the formation of the graphene film. Specifically, graphene growth can be controlled from F-LG (few layer graphene) down to 2-LG (2-layer graphene) and 1-LG (1-layer graphene). More than one texture can be created to form maskless patterns of graphene. Once the graphene layer(s) are grown, the film can be released from the metal and applied to any form and shape of rigid or flexible substrate for a variety of different applications where graphene cannot be normally grown directly.
