Abstract: A method includes growing a graphene layer on a metal layer, intercalating a first material between the metal layer and the graphene layer by heating the first material at a first pressure and a first temperature, and intercalating a second material between the metal layer and the graphene layer by heating the second material at a second pressure different from the first pressure and a second temperature different from the first temperature. Accordingly, the first material and the second material are chemically bonded to each other to form an insulating layer, and the insulating layer may be between the metal layer and the graphene layer.

Abstract: A conductor including a graphene layer and a method of manufacturing the conductor are provided. The conductor may further include a nano pattern disposed on a substrate, and the graphene layer may be formed on the nano pattern. The nano pattern may have any various shapes and include a material that interacts with the graphene layer. The nano pattern and the graphene layer included in the conductor may interact with each other, such that the electric characteristics of the conductor are maintained while the heat transfer characteristics thereof are improved.
