Epitaxial Graphene Nanoribbons on Bunched Steps of a 6H-SiC(0001) Substrate: Aromatic Ring Pattern and Van Hove Singularities

M. Ridene, T. Wassmann, E. Pallecchi +3

We report scanning tunneling microscopy and spectroscopy investigation of graphene nanoribbons grown on an array of bunched steps of a 6H-SiC(0001) substrate. Our scanning tunnelin…

Graphene microwave transistors on sapphire substrates

E. Pallecchi, C. Benz, A. C. Betz +3

We have developed metal-oxide graphene field-effect transistors (MOGFETs) on sapphire substrates working at microwave frequencies. For monolayers, we obtain a transit frequency up…
