▎ 摘　　要

NOVELTY - Graphene synthesis method comprises: disposing a substrate including a metal thin film in an inner space of a graphene synthesis chamber (1500); depressurizing the inner space; supplying a gas including carbon into the inner space using a gas supplier; and irradiating a light to the inner space to heat the substrate using a main heating unit (1140), where a first auxiliary heating unit and a second auxiliary heating unit are disposed at both sides of the substrate, respectively, and spaced apart from each other so as to define an auxiliary space therebetween for synthesizing graphene on the substrate, and the substrate is disposed in the auxiliary space, and spaced apart from the first auxiliary heating unit and the second auxiliary heating unit. USE - The method is useful for synthesizing graphene. DESCRIPTION OF DRAWING(S) - The figure shows a cross-sectional view of a graphene synthesis chamber.
