Epitaxial Graphene on Metals
In this chapter, we review the recent results on graphene films epitaxially grown on 3d 5d transition-metal surfaces focussing mainly on their atomic structure, aspects of chemical interaction both with the substrate and with adsorbates and the electronic structure of graphene at the interface. We discuss a possibility to prepare sandwich-like structures in the form of intercalates as a possibl...
متن کاملTowards nanoprinting with metals on graphene
Graphene and carbon nanotubes are envisaged as suitable materials for the fabrication of the new generation of nanoelectronics. The controlled patterning of such nanostructures with metal nanoparticles is conditioned by the transfer between a recipient and the surface to pattern. Electromigration under the impact of an applied voltage stands at the base of printing discrete digits at the nanosc...
متن کاملTailoring the thermal Casimir force with graphene
The Casimir interaction is omnipresent source of forces at small separations between bodies, which is difficult to change by varying external conditions. Here we show that graphene interacting with a metal can have the best known force contrast to the temperature and the Fermi level variations. In the distance range 50–300 nm the force is measurable and can vary a few times for graphene with a ...
متن کاملPoint defects on graphene on metals.
Understanding the coupling of graphene with its local environment is critical to be able to integrate it in tomorrow's electronic devices. Here we show how the presence of a metallic substrate affects the properties of an atomically tailored graphene layer. We have deliberately introduced single carbon vacancies on a graphene monolayer grown on a Pt(111) surface and investigated its impact in t...
متن کاملPhonon dynamics of graphene on metals.
The study of surface phonon dispersion curves is motivated by the quest for a detailed understanding of the forces between the atoms at the surface and in the bulk. In the case of graphene, additional motivation comes from the fact that thermal conductivity is dominated by contributions from acoustic phonons, while optical phonon properties are essential to understand Raman spectra. In this art...
