报告摘要

In this talk, I will briefly summarize research and progresses at SIMIT-CAS on the synthesis of 2D materials, including the growth of inch-sized graphene single crystal on CuNi foil, our systematic research on the direct graphene growth on hexagonalboron nitride single crystal flakes (h-BN) and graphene growth on single crystal germanium substrate etc. Besides a general overview, I will mainly talk about two latest progresses. One progress is on the epitaxial growth of 6-inch single crystalline graphene on a Cu/Ni (111) film at temperature down to 7500C. The Cu/Ni film deposited on sapphire were annealed to form a single crystalline alloy CuNi (111) film, allowing for oriented growth of ultra-flat graphene film. The high catalytic power reduced the growth temperature down to 750C. The quality of the film was justified by FET device, with carrier mobility up to ～ 9700 cm2v-1s-1 at room temperature. Another progress is on the controllable synthesis of uniform multilayer h-BN films on sapphire substrate, using molten Fe-B as a catalyst and nitrogen as precursor. The molten Fe-B supplied boron source, and dissociated nitrogen at the same time, resulting in the high quality growth of h-BN on sapphire substrate with controllable thickness.

会议简介

The 5th International Conference on 2D Materials and Technology was held in Suzhou, China, October 21-24, 2019. Prestigious scientists presented and stimulated discussions over some inherent topics of the ICON-2DMAT, including the Synthesis and Characterizations, Physics and Chemistry, Device applications, Theory and Modeling of 2D materials and heterostructures, etc. And, a special session related to the Vacuum Interconnected Nanotech Workstation (Nano-X) in Suzhou Institute of Nano-Tech and Nano-Bionics was be set up, which was dedicated to introduce a large scientific facility to 2D materials and technology. Specific forums and some other Symposia co-organized with preeminent academic publishers was be also established to foster academic and business networking.
