在Ir（111）和Ru（0001）表面上使用唯一的前体腺嘌呤合成了氮（N）掺杂的石墨烯材料。利用X射线光电子能谱和扫描隧道显微镜（STM）对所得的N掺杂石墨烯材料进行了表征。几个石墨和吡啶N掺杂剂已确定在原子尺度上结合STM测量和STM模拟基于密度泛函理论计算。
Nitrogen (N) doped graphene materials have been synthesized using the sole precursor adenine on the Ir(111) and Ru(0001) surfaces. X-ray photoelectron spectroscopy and scanning tunneling microscopy (STM) have been used to characterize the obtained N-doped graphene materials. Several graphitic and pyridinic N dopants have been identified on the atomic scale by combining STM measurements and STM simulations based on density functional theory calculations.
