▎ 摘  要

NOVELTY - An apparatus for fabricating graphene comprises: optionally rotating unit configured to rotate a substrate; a first light source configured to irradiate a graphite oxide layer on a substrate; a second light source configured to further irradiate the irradiated graphite oxide layer; and a control unit (330) configured to control an order of irradiation from the first light source and the second light source. The first light source is configured to produce laser light, and the second light source is configured to produce flash light. The flash light includes Xenon flash or UV flash. USE - For fabricating graphene (claimed). ADVANTAGE - In the present apparatus, both a laser light source and a flash light source are used in the fabrication of graphene to reduce a graphite oxide layer. Accordingly, it is possible to reduce a large area of the graphite oxide layer quickly and more evenly as compared to a method in which only one type of light source is used. By using the present apparatus, graphene can be mass produced in a high quality at a lower cost. In addition, the graphene produced by the present apparatus has superior characteristics than graphene produced by other methods. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for fabricating graphene involving obtaining a graphite oxide layer on a substrate; and exposing the graphite oxide layer with light from a first light source and light from a second light source, where the exposing of the graphite oxide layer with light from the first light source comprises moving the first light source above the graphite oxide layer, or moving the graphite oxide layer and the substrate under the first light source. DESCRIPTION OF DRAWING(S) - The figure shows a diagram illustrating an apparatus for fabricating graphene. First light irradiation unit (310) Second light irradiation unit (320) Control unit (330)
