  • Patent number: 9379000
    Abstract: The present invention relates to a method for producing a nanocarbon film using a hybrid substrate with which a nanocarbon film free from defects can be produced at low cost. This method is characterized in forming an ion implantation region by implanting ion into a single crystal silicon carbide substrate from a surface thereof and after bonding together the surface of the silicon carbide substrate implanted with ion and a surface of a base substrate, releasing the silicon carbide substrate at the ion implanted region to produce a hybrid substrate in which a thin film that includes the single crystal silicon carbide is transferred onto the base substrate, and then heating the hybrid substrate to sublime silicon atoms from the thin film that includes the single crystal silicon carbide so as to obtain the nanocarbon film.

  • Patent number: 9216559
    Abstract: A method for transferring graphene nondestructively and at a low cost. In the method, a graphene is used whose surface is coated with transferring media and whose original substrate is an electrode, the electrode is placed into an electrolyte, and the graphene is separated from the original substrate by means of the driving force of bubbles and the gas intercalation produced on the graphene electrode surface during electrolysis. Then, the graphene coated with transferring media is nondestructively combined with a target substrate. The transferring media is removed so as to transfer the graphene to the target substrate nondestructively. The transferring method results in no damage or loss with respect to the graphene and the original substrate, and the original substrate can be re-used. Furthermore, the method is easy to perform, works quickly, is easy to control, and is pollution-free.
