Abstract: A graphene doped with different dopants and a method for preparing the same are disclosed. A method for preparing a multi-doped graphene includes: mixing a metal-based dopant and at least one organic-based dopant to prepare a doping solution; stacking a graphene layer on a substrate; and doping the graphene layer with the doping solution that includes the metal-based dopant and the at least one organic-based dopant. The method allows maintaining the transparency of the prepared graphene and minimizing the sheet resistance of the graphene while not damaging a substrate on which the graphene is stacked.
