    Editor: Date:2020-12-27 Hits:43

         On the afternoon of December 25, 2020, the “Qiushi Material Science Forum of Zhejiang University” sponsored by Department of Materials was held in Yuanwang Pavilion, Cao Guangbiao high-tech building. Researcher Liu Kaihui of Department of physics of Peking University was invited to give a report entitled “Atomic manufacturing and application of meter-scale two-dimensional single crystal”.

    The forum was presided over by Associate Professor Ren Zhaohui. Before the beginning of the report, Associate Professor Ren Zhaohui gave a brief introduction to researcher Liu Kaihui and his work.

    In the report, researcher Liu Kaihui first introduced the technical breakthrough of the research group in the manufacturing of large-size single crystal copper foil. Researcher Liu said that at present, the research group has been able to batch prepare up to 35 kinds of large-size high index plane copper foils, providing rich substrates for the subsequent preparation of large-size two-dimensional single crystals. At present, this technology not only provides the preliminary basis for the follow-up research of the research group, but also has realized industrialization, providing large quantities of high-quality single crystal copper foil for domestic enterprises.

    Then, researcher Liu introduced the work of the research group on the preparation of large-scale two-dimensional single crystal. At present, the research group has been able to prepare 0.5 meter long single crystal graphene, and the related technology can also be used to prepare nonlinear two-dimensional materials and devices. Professor Liu Kaihui's high-density knowledge and passionate report aroused great interest of teachers and students.

    After the end of the report, the teachers and students on the scene actively asked researcher Liu Kaihui questions, and researcher Liu also shared his experience in the process of scientific research. Researcher Liu Kaihui is full of academic enthusiasm and positive academic spirit, which impressed the students here.

    Finally, Han Gaorong, Dean of the Department of Materials, presented Professor Liu Kaihui with a commemorative cup for the keynote speaker of Qiushi Material Science Forum of Zhejiang University.
