Abstract The thermal treatment of a monolayer of 1-naphthylmethylamine (NMA) on Ni(1 1 1) surface reveals a complex chemistry promoted by the high surface reactivity. Both the amino-terminated functional group and the naphthalene body of NMA undergo a progressive dehydrogenation, which eventually leads to the coalescence of the molecules. As a result, 2D structures of increasing size are synthesized on the surface, characterized by a graphene-like lattice in which nitrogen atoms are mainly incorporated as pyridinic substitutional defects. In this paper, we show the evidence of the formation of extended nitrogen-doped graphene (N-GR) domains at temperatures as low as 300 °C, with band dispersion measurements that reveal p-type doping.

Ni(111) 上的甲胺封端分子：氮掺杂石墨烯的低温合成途径

摘要 Ni(1 1 1) 表面单层1-萘基甲胺(NMA) 的热处理揭示了由高表面反应性促进的复杂化学。NMA 的氨基末端官能团和萘体都经过逐步脱氢，最终导致分子聚结。结果，在表面上合成了尺寸越来越大的二维结构，其特征是类似石墨烯的晶格，其中氮原子主要作为吡啶取代缺陷掺入。在本文中，我们展示了在低至 300 °C 的温度下形成扩展的氮掺杂石墨烯 (N-GR) 域的证据，带色散测量揭示了 p 型掺杂。
