    Controllable sliding transfer of wafer‐size graphene
    (Hoboken, NJ : Wiley, 2016) Lu, Wenjing; Zeng, Mengqi; Li, Xuesong; Wang, Jiao; Tan, Lifang; Shao, Miaomiao; Han, Jiangli; Wang, Sheng; Yue, Shuanglin; Zhang, Tao; Hu, Xuebo; Mendes, Rafael G.; Rümmeli, Mark H.; Peng, Lianmao; Liu, Zhongfan; Fu, Lei
    The innovative design of sliding transfer based on a liquid substrate can succinctly transfer high‐quality, wafer‐size, and contamination‐free graphene within a few seconds. Moreover, it can be extended to transfer other 2D materials. The efficient sliding transfer approach can obtain high‐quality and large‐area graphene for fundamental research and industrial applications.

    High-mobility graphene on liquid p-block elements by ultra-low-loss CVD growth
    (London : Nature Publishing Group, 2013) Wang, Jiao; Zeng, Mengqi; Tan, Lifang; Dai, Boya; Deng, Yuan; Rümmeli, Mark; Xu, Haitao; Li, Zishen; Wang, Sheng; Peng, Lianmao; Eckert, Jürgen; Fu, Lei
    The high-quality and low-cost of the graphene preparation method decide whether graphene is put into the applications finally. Enormous efforts have been devoted to understand and optimize the CVD process of graphene over various d-block transition metals (e.g. Cu, Ni and Pt). Here we report the growth of uniform high-quality single-layer, single-crystalline graphene flakes and their continuous films over p-block elements (e.g. Ga) liquid films using ambient-pressure chemical vapor deposition. The graphene shows high crystalline quality with electron mobility reaching levels as high as 7400 cm2 V−1s−1 under ambient conditions. Our employed growth strategy is ultra-low-loss. Only trace amounts of Ga are consumed in the production and transfer of the graphene and expensive film deposition or vacuum systems are not needed. We believe that our research will open up new territory in the field of graphene growth and thus promote its practical application.
