▎ 摘　　要

NOVELTY - Method for improving the carrier concentration of graphene involves (1) manufacturing the graphene (2) performing secondary uniform glue to the substrate of graphene uniformly gluing and baking substrate of the chip with PMMA solution for graphene time; then using the mixed doping agent to perform the second uniform glue for the graphene time of uniform glue, where the mixed doping agent is PMMA doped with 2,3,5,6-Tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ), (3) in glove box, graphene the chip after the secondary uniform glue, (4)adjusting and controlling graphene chip, to reduce the carrier concentration of the graphene. USE - Encapsulation method for improving graphene of carrier concentration. ADVANTAGE - The packaging method not only effectively isolates the air on the surface of the graphene chip chip, reduces the influence of water in the air, oxygen to the graphene of the carrier concentration of the chip, and reduces the concentration of carrier graphene. The graphene chip packaging structure is small, it will not affect the transportation and measurement, and it does not need to be placed in the glove box to store, which is greatly convenient for the storage of chip. In addition, the packaging method is simple in operation process, less in use and cheap, raw material it is suitable for popularization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for packaging method for improving the stability of the concentration of the carrier graphene to claim.
