▎ 摘  要

NOVELTY - Manufacture of ordered graphene structure involves exposing substrate to laser beam (110) to locally melt portion of the substrate, exposing the substrate to laser beam in presence of carbon source to form nucleation site (130) for graphene crystal (140), and moving the substrate or laser beam relative to other, or decreasing laser beam power, in order to increase the size of the graphene crystal. USE - Manufacture of ordered graphene structure used for multitouch capacitive panels. ADVANTAGE - The method enables manufacture of ordered graphene structure having high crystallinity and reduced polycrystallinity, prevents oxide formation and removes oxygen from the substrate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for apparatus for growing graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the engineered graphene grain domains relative to the laser-induced nucleation sites.
