Graphene–metals interfaces are investigated in many subject areas both applicative and speculative. The interest mainly
stems from the possibility for CVD synthesis of large area graphene on metals. In this case the metal acts as a catalyst for
complete dehydrogenetaion of hydrocarbon precursors that leaves carbon behind at the surface. Such bilayer are also
very appealing for surface plasmon resonance devices, since graphene acts both as a protective layer and biorecognition
element. Several pairs of graphene–metal interfaces have been studied in terms of SPR performance and physicalchemical
properties at the interface. With regard to this last aspect, NEXAFS spectroscopy is a powerful method to study
single-, double-, and few- layers graphene and to illustrate any evolution of the electronic states.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
