The present invention relates to graphene and, particularly, to a method for doping graphene using substrate surface modification, a method for manufacturing a graphene composite electrode using graphene and inorganic matter, and a graphene structure comprising the same. The method for doping graphene according to an embodiment of the present invention may comprise the steps of: forming, on a substrate, a precursor polymer layer for doping; and positioning graphene on the substrate on which the precursor polymer layer is formed. In addition, the method for manufacturing a graphene composite electrode according to an embodiment of the present invention may comprise the steps of: forming graphene on catalyst metal; forming a transparent conductive oxide on the graphene; crystallizing the transparent conductive oxide by applying heat of 150&#xb0; C. or higher; and transferring, to a final substrate, a composite electrode consisting of the graphene and the transparent conductive oxide.

Method for doping graphene, method for manufacturing graphene composite electrode, and graphene structure comprising same

The present invention provides a method for manufacturing graphene, said graphene, and an apparatus for manufacturing same. The method for manufacturing graphene comprises the steps of: loading a catalytic metal layer into a chamber; applying tensile force to the catalytic metal layer; and forming graphene on the catalytic metal layer by supplying a carbon source into the chamber while the tension is applied to the catalytic metal layer. Therefore, the size of the grains on the catalytic metal layer can be increased by applying tension to the catalytic metal layer, and high quality uniform graphene can be grown through the use of the catalytic metal layer.
