Graphene is a two-dimensional network in which sp(2)-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 (N-2(AA)). Scanning tunneling
microscopy and spectroscopy (STM and STS) of NG revealed the presence of
localized states in the conduction band induced by N-2(AA)-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.
