| titleOfInvention | Device and method for testing contact electrical characteristics of graphene nanocrystalline carbon film |
| abstract | The invention discloses a device and a method for testing contact electrical characteristics of a graphene nano-crystal carbon film, wherein the device comprises a metal base, a P-type silicon substrate, the graphene nano-crystal carbon film and a conductive probe which can be contacted with the graphene nano-crystal carbon film in a stacked mode, the metal base and the graphene nano-crystal carbon film are electrically connected through conductive silver paste, and the conductive probe is electrically connected with the metal base. According to the method, based on different contact stages of the conductive probe and the graphene nano-crystal carbon film, a constant voltage mode and a variable voltage mode are adopted to respectively carry out contact electrical characteristic tests on the graphene nano-crystal carbon film, and corresponding electrical characteristic data are obtained. The contact electrical characteristics of the graphene nano-crystal carbon film are tested, and the larger the average nano-crystal size of the graphene nano-crystal carbon film is, the better conductivity is shown, and the method has important significance for the application of the graphene nano-crystal carbon film on the surface of a micro-nano device. |
