中国科学院上海微系统与信息技术研究所的研究人员在世界上首次通过引入气态催化剂的方法成功实现了石墨烯单晶在六角氮化硼表而的高取向快速生长。研究人员在前期掌握了石墨烯形核控制技术、确定了单晶和衬底的取向关系的基础上,以乙炔为碳源,创新性地引入硅烷作为催化 Researchers at the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, have successfully achieved the high-orientation rapid growth of graphene single crystals on a hexagonal boron nitride table by introducing a gaseous catalyst for the first time in the world. Researchers grasped the graphene nucleation control technology in the early stage and determined the orientation relationship between the single crystal and the substrate.
