Fluorescence from graphene nanoribbons of well-defined structure

Synthesis of structurally well-defined and liquid-phase-processable graphene nanoribbons.

The properties of graphene nanoribbons (GNRs) make them good candidates for next-generation electronic materials. Whereas 'top-down' methods, such as the lithographical patterning of graphene and the unzipping of carbon nanotubes, give mixtures of different GNRs, structurally well-defined GNRs can be made using a 'bottom-up' organic synthesis approach through solution-mediated or surface-assist...

Unveiling the magnetic structure of graphene nanoribbons.

We perform magnetotransport measurements in lithographically patterned graphene nanoribbons down to a 70 nm width. The electronic spectrum fragments into an unusual Landau levels pattern, characteristic of Dirac fermion confinement. The two-terminal magnetoresistance reveals the onset of magnetoelectronic subbands, edge currents and quantized Hall conductance. We bring evidence that the magneti...

Facile hydrothermal preparation of graphene oxide nanoribbons from graphene oxide.

Graphene oxide nanoribbons (GONR) with regular edges have been prepared by a facile hydrothermal method. The relatively high yield and convenient preparation of GONR eventually make graphene nanoribbons (GNR) accessible in the field of composite materials where bulk quantities of nanoribbons are required.

Graphene Nanoribbons: from chemistry to circuits

The Y-chart is a powerful tool for understanding the relationship between various views (behavioral, structural, physical) of a system, at different levels of abstraction, from high-level, architecture and circuits, to low-level, devices and materials. We thus use the Y-chart adapted for graphene to guide the chapter and explore the relationship among the various views and levels of abstraction...
