▎ 摘　　要

NOVELTY - Producing graphene, comprises: fixing (210) a seed crystal to a support substrate such that the seed crystal faces downwardly from the support substrate about a location; providing (220) a feedstock adjacent to the seed crystal about the location; and applying (230) a laser beam to heat at least a portion of the seed crystal and at least a portion of the feedstock about the location, where a graphene crystal is formed that hangs downwardly from the surface of the support structure. USE - The method is useful for producing graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) an apparatus for producing graphene, comprising: the seed crystal fixed to the support substrate; the feedstock injector configured to provide the feedstock adjacent to the seed crystal about the location; the laser configured to selectively generate the laser beam; and beam shaping optics configured to couple the laser beam to at least a portion of the seed crystal and at least a portion of the feedstock about the location to form a downwardly hanging graphene crystal; and (2) an article comprising: a computer program product having stored in it instructions that, when executed by a processing unit, configures the processing unit to provide a feedstock adjacent to a seed crystal about the location, where the seed crystal is fixed to a support substrate about the location such that the seed crystal faces downwardly from the support substrate; and selectively provides the laser beam. DESCRIPTION OF DRAWING(S) - The figure shows an illustration of a flow chart of a method for producing graphene.
