石墨烯与衬底之间的表面界面特性研究及其对异质结构的影响是当前科学研究的前沿热门领域之一，而同步辐射原位技术在此领域的研究中具有先天的优势。基于同步辐射X射线衍射技术，本项目拟探索不同衬底生长石墨烯的表面界面特性及多维度原位实时结构演化。主要内容如下：(1)搭建完备的石墨烯原位化学气相沉积研究平台，满足不同条件及衬底上石墨烯的原位生长实时观测等研究需求;(2)基于自主搭建的原位研究装置，发展秒级时间分辨的掠入射二维衍射技术，进行多晶金属衬底(镍、铜等)上生长石墨烯的原位观测与调控，研究石墨烯层间相互作用、微结构瞬时演变及与衬底的相互作用；(3)发展埃尺度空间分辨的同步辐射表面衍射技术，研究单晶衬底（硅、BN）上单层或少层石墨烯生长过程中微结构演变，探索石墨烯与单晶衬底的表面界面相互作用及对异质结构的影响。项目的实施期望推动石墨烯表面界面特性的深入研究和同步辐射关联技术的应用发展。

The study on the surface and interface characteristics of graphene with different substrates and the impacts on the heterostructure have become one of the frontier scientific research areas. Synchrotron Radiation in situ techniques have unique advantage in this field. Based on Synchrotron Radiation X-ray diffraction techniques, in this project, we intend to in-situ explore the surface and interface structure evolution of graphene. The main contents are as follows: (1) we are planning to build an in-situ chemical vapor deposition chamber and platform at beamline BL14B1 of Shanghai Synchrotron Radiation Facility;（2）Basing on the in-situ chemical vapor deposition platform, we will develop the two-dimensional grazing-incidence X-ray diffraction technique. Focusing on the in-situ graphene deposition on polycrystalline metal substrates (Ni, Cu), we will study the interlayer interaction of graphene, instantaneous microstructure evolution and the graphene-substrate interaction; (3) The development of Synchrotron Radiation surface diffraction techniques with high space resolution (0.1nm). We will study the surface and interface structure of graphene on single crystal substrates (Si, BN), to explore the in-plane structure evolution and interface interaction. Through this project, we will provide a frontier in-situ Synchrotron Radiation chemical vapor deposition growth platform and x-ray surface diffraction techniques for domestic and international researchers.
