Method for directly synthesizing graphene on surface of target object and device including graphene prepared using the method

A method for directly synthesizing graphene on a surface of a target object, comprising:

• forming a non-metal layer on a support substrate;
• disposing the target object in a space above the support substrate;
• and
• injecting a carbon precursor to form graphene on the surface of the target object to synthesize a graphene film,
• wherein the graphene is nucleated and grown on the surface of the target object by a decomposition of the carbon precursor, the carbon precursor is decomposed by heat with catalytic assistance from the non-metal layer to diffuse a carbon atom into the space above the support substrate, and the carbon atom from the decomposition of the precursor is anchored on the surface of the target object to form the graphene film,
• wherein the target object is located within the space above the support substrate comprising the diffused carbon atom.
