  • Patent number: 9490040
    Abstract: Disclosed are boron/nitrogen co-doped graphene for semiconductor applications and a method for producing the same. The boron/nitrogen co-doping allows the use of the doped graphene in a wider variety of applications, including semiconductors. In contrast, graphene structures produced by conventional methods have good physical, chemical, and electrical stability but cannot be used in semiconductor applications due to the absence of band gaps therein. In addition, the boron/nitrogen co-doping makes the doped graphene highly dispersible in organic solvents.

  • Publication number: 20160137507
    Abstract: A graphene transfer method using water vapor-assisted determination of CVD-grown graphene film on the Cu foil. By using the polymer film as a supporting layer, we found that graphene can be directly detached from the Cu foil as a consequence of water intercalated at the graphene-Cu interface(s), by a ‘dry transfer’ method. The delaminated graphene films are continuous over large area. This nondestructive method also worked for the transfer of graphene grown on a Cu single crystal without sacrificing the expensive crystal, thus affording the possibility of producing high-quality graphene and reusing the substrate. The Cu foil and single crystal can both be repeatedly used for many times, which may reduce the cost of graphene synthesis and is environmentally more benign. Our method affords the advantages of high efficiency, likely industrial scalability, minimal use of chemicals, and the reusability of the Cu foil in multiple growth and delamination cycles.
