摘要：

Substitutional doping of graphene nanoribbons (GNRs) with heteroatoms is a principal strategy to fine-tune the electronic structure of GNRs for future device applications. Here, we report the fabrication and nanoscale characterization of atomically precise N = 13 armchair GNRs featuring regioregular edge-doping with sulfur atoms (S-13-AGNRs) on a Au(111) surface. Scanning tunneling spectroscopy and first-principle calculations reveal modification of the electronic structure of S-13-AGNRs when compared to undoped N = 13 AGNRs.
