  • 来源:盖景刚教授个人网站 2020-02-17
  • Graphene, the thinnest, strongest, and stiffest material with

    exceptional thermal conductivity and electron mobility, has increasingly

    received worldwide attention in the past few years. These unique properties may

    lead to novel or improved technologies to address the pressing global

    challenges in many applications including transparent conducting electrodes, fi

    eld effect transistors, fl exible touch screen, single-molecule gas detection,

    desalination, DNA sequencing, osmotic energy production, etc. To realize these applications,

    it is necessary to transfer graphene fi lms from growth substrate to target

    substrate with large-area, clean, and low defect surface, which are crucial to

    the performances of large-area graphene devices. This critical review assesses

    the recent development in transferring large-area graphene grown on Fe, Ru, Co,

    Ir, Ni, Pt, Au, Cu, and some nonmetal substrates by using various synthesized

    methods. Among them, the transfers of the most attention kinds of graphene

    synthesized on Cu and SiC substrates are discussed emphatically. The advances

    and the main challenges of each wet and dry transfer method for obtaining the

    transferred graphene film with large-area, clean, and low defect surface are

    also reviewed. Finally, the article concludes the most promising methods and

    the further prospects of graphene transfer.
