在这个角度来看，我们提出了一个概述最近的基础研究的性质之间的相互作用的单个金属原子和金属簇和共轭表面的石墨烯和碳纳米管，特别关注的电子结构和化学键合在金属石墨烯界面。我们讨论了石墨材料的有机金属配合物的相关性，这些相互作用的基本理解和它们在原子电子学中的应用，如原子互连，高迁移率有机金属晶体管器件，高频电子器件，有机金属催化（氢燃料产生光催化水分解，燃料电池，氢化），自旋电子学，存储器设备，和下一代能源设备。我们触及在金属上生长的化学气相沉积（CVD）石墨烯，其表面的反应性，以及其作为不对称石墨烯功能化化学（双Janus盘）的模板的用途。我们强调了一些最新的进展，从金属覆盖层沉积在石墨烯和单壁碳纳米管薄膜的角度来理解金属和石墨烯表面之间的相互作用的性质。最后，我们评论该领域面临的主要挑战和技术应用的机会。
In this Perspective, we present an overview of recent fundamental studies on the nature of the interaction between individual metal atoms and metal clusters and the conjugated surfaces of graphene and carbon nanotube with a particular focus on the electronic structure and chemical bonding at the metal graphene interface. We discuss the relevance of organometallic complexes of graphitic materials to the development of a fundamental understanding of these interactions and their application in atomtronics as atomic interconnects, high mobility organometallic transistor devices, high-frequency electronic devices, organometallic catalysis (hydrogen fuel generation by photocatalytic water splitting, fuel cells, hydrogenation), spintronics, memory devices, and the next generation energy devices. We touch on chemical vapor deposition (CVD) graphene grown on metals, the reactivity of its surface, and its use as a template for asymmetric graphene functionalization chemistry (ultrathin Janus discs). We highlight some of the latest advances in understanding the nature of interactions between metals and graphene surfaces from the standpoint of metal overlayers deposited on graphene and SWNT thin films. Finally, we comment on the major challenges facing the field and the opportunities for technological applications.
