石墨烯是一种二维网络，其中sp2杂化的碳原子排列在两个不同的三角形子晶格（A和B）中。通过将氮原子引入石墨烯，其物理化学性质可以根据子晶格内的掺杂配置而显著改变。在这里，我们描述了大面积，高结晶单层N-掺杂石墨烯（NG）片的合成通过大气压化学气相沉积，产生一个独特的N-掺杂的网站组成的两个准相邻的取代氮原子在同一个石墨烯子晶格（N2 AA）。NG的扫描隧道显微镜和光谱（STM和STS）揭示了由N2 AA掺杂引起的导带中的局域态的存在，这是由从头计算证实的。此外，我们首次证明了NG可以通过高度改进的石墨烯增强拉曼散射来有效地探测有机分子。
Graphene is a two-dimensional network in which sp2-hybridized carbon atoms are arranged in two different triangular sub-lattices (A and B). By incorporating nitrogen atoms into graphene, its physico-chemical properties could be significantly altered depending on the doping configuration within the sub-lattices. Here, we describe the synthesis of large-area, highly-crystalline monolayer N-doped graphene (NG) sheets via atmospheric-pressure chemical vapor deposition, yielding a unique N-doping site composed of two quasi-adjacent substitutional nitrogen atoms within the same graphene sub-lattice (N2AA). Scanning tunneling microscopy and spectroscopy (STM and STS) of NG revealed the presence of localized states in the conduction band induced by N2AA-doping, which was confirmed by ab initio calculations. Furthermore, we demonstrated for the first time that NG could be used to efficiently probe organic molecules via a highly improved graphene enhanced Raman scattering.
