Abstract: Provided is a method of forming graphene having an increased grain size. In the method, a substrate including a catalyst layer formed of a transition metal is loaded into a chamber and a gaseous carbon source is supplied into the chamber. A continuous heat treatment in which the catalyst layer is locally heated while moving a heated area of the catalyst layer is performed to dissolve a carbon component in the catalyst layer and extract graphene on a surface of the catalyst layer from the dissolved carbon component.
