TITLE: Engineering the Electronic and Chemical Properties of Graphene via Functionalization and Intercalation.
SPEAKER: Liv Hornekær, Dept. Physics and Astronomy & interdisciplinary
Nanoscience Center- iNANO, Aarhus University, Denmark.
ABSTRACT: Extensive control of the electronic and chemical properties of graphene on Ir(111) is available through chemical functionalization  and intercalation. Combined Scanning Tunneling Microscopy, (Standing Wave) X-ray Photoemmission Spectroscopy and Density Functional Theory calculations show how on one hand, functionalization structures can be controlled via intercalation, while conversely, intercalation can be hindered via chemical functionalization. Furthermore, unique oxygen functionalization structures  and molecular hydrogen dissociative adsorption pathways  are available in this system. Overall this allows for extensive control of electronic properties for band gap engineering , as well as control of the graphene-substrate interaction, providing proof-of-principle pathways to e.g. enhance the coating properties of graphene on metal surfaces .
