Synthesis by chemical vapor deposition of nitrogen-doped graphitic nanoribbons (Nx-GNRs) is reported using pyrazine as a N precursor. Morphological, physico-chemical, and electrical characterization of nitrogen-doped graphitic nanoribbons reveal unique characteristics associated with doping sites, such as increased reactivity and changes in the electrical response towards semiconducting-like features. These results are confirmed using first-principle theoretical studies of N-doped graphene nanoribbons.
