Local transport measurements on epitaxial graphene

Disordered Fermi liquid in epitaxial graphene from quantum transport measurements.

We have performed magnetotransport measurements on monolayer epitaxial graphene and analyzed them in the framework of the disordered Fermi liquid theory. We have separated the electron-electron and weak-localization contributions to resistivity and demonstrated the phase coherence over a micrometer length scale, setting the limit of at least 50 ps on the spin relaxation time in this material.

Atomic-scale transport in epitaxial graphene.

The high carrier mobility of graphene is key to its applications, and understanding the factors that limit mobility is essential for future devices. Yet, despite significant progress, mobilities in excess of the 2×10(5) cm(2) V(-1) s(-1) demonstrated in free-standing graphene films have not been duplicated in conventional graphene devices fabricated on substrates. Understanding the origins of t...

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...
