The recent discovery of graphene has sparked much interest, thus far focused on the peculiar electronic structure of this material, in which charge carriers mimic massless relativistic particles. However, the physical structure of graphene—a single layer of carbon atoms densely packed in a honeycomb crystal lattice—is also puzzling. On the one hand, graphene appears to be a strictly two-dimensional material, exhibiting such a high crystal quality that electrons can travel submicrometre… 

Ultraflat graphene

Graphene monolayers that are flat down to the atomic level are fabricated by deposition on the atomically flat terraces of cleaved mica surfaces, indicating the suppression of any existing intrinsic ripples in graphene.

Free-standing graphene at atomic resolution.

The presence of free-standing, single-layer graphene is confirmed with directly interpretable atomic-resolution imaging combined with the spatially resolved study of both the pi --> pi* transition and the pi + sigma plasmon.

Properties of graphene: a theoretical perspective

The electronic properties of graphene, a two-dimensional crystal of carbon atoms, are exceptionally novel. For instance, the low-energy quasiparticles in graphene behave as massless chiral Dirac

Thermal stability of graphene edge structure and graphene nanoflakes.

Graphene nanoflakes are stable to being heated and do not under any conditions used here transform to CNTs, but do not remain strictly 2D as at finite temperatures, they undergo extensive vibrational motion and remain buckled if annealed and then quenched to room temperature.

Localized electrons in graphene nanostructures

Graphene consists of a single layer of carbon atoms arranged in a honeycomb lattice. Its special mechanical, thermal, optical and electronic properties make it a promising material for a wide range

Graphene: from materials science to particle physics

Since its discovery in 2004, graphene, a two-dimensional hexagonal carbon allotrope, has generated great interest and spurred research activity from materials science to particle physics and vice

Suspended Graphene: a bridge to the Dirac point

The recent discovery of methods to isolate graphene 1-3 , a one-atom-thick layer of crystalline carbon, has raised the possibility of a new class of nano-electronics devices based on the

Intrinsic ripples in graphene.

It is found that ripples spontaneously appear owing to thermal fluctuations with a size distribution peaked around 80 A which is compatible with experimental findings and might be due to the multiplicity of chemical bonding in carbon.

Graphene weak-localization magnetoresistance is strongly suppressed and, in some cases, completely absent, due to mesoscopic corrugations of graphene sheets which can cause a dephasing effect similar to that of a random magnetic field.
