Novel electronic behaviors in graphene nanostructures
Recently, it has been shown that graphene can be combined with a variety of nanoscale systems, such as other two-dimensional crystals, to form novel electronic nanostructures. These systems inherit the unique characteristics of graphene, such as high mobility, Berry phase, photoresponse mediated by …

Anomalous Hall effect and persistent valley currents in graphene p-n junctions/
… of this unusual effect for charge carriers in graphene nanostructures. The Hall effect is nonzero in each valley but is of opposite signs in different valleys, giving rise to charge-neutral valley currents. Our analysis reveals that p-n junctions in graphene support persistent valley currents …

Molecular Plasmonics: Graphene Plasmons in the Picoscale Limit
Doped graphene supports surface plasmons in the mid- to far-infrared that are both electrically and spatially tunable. Graphene has been shown to enable greater spatial confinement of the plasmon and fewer losses than typical noble metals. Reduced-dimensional graphene structures, including …
