Paper in ACS Nano

We introduce a novel procedure to prepare a well-defined single atom substitutional boron doped and boron-nitrogen co-doped epitaxial graphene grown on silicon carbide. On top of this, we provide an extensive characterization of electronic and chemical properties using different experimental techniques (atomically resolved UHV AFM and STM, XPS and NEXAFS) supported by theoretical calculations (total energy DFT and STM). We demonstrate that STM images can provide a robust chemical resolution between B and N dopant due to quantum interference effect driven by peculiar local electronic properties of N dopants. Finally, atomically resolved 3D force mapping allows us to analyze the local chemical properties of N and B dopant with respect to pristine graphene. We found distinct interaction between N,B-dopants and graphene, which is mainly caused by a weak electrostatic interaction due to charge transfer between the dopant and graphene, respectively. The presence of the weak electrostatic force can play significant role in graphene functionalization using polar molecules.
