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… Expand
Chapter 7 Low-Energy Electronic Structure of Graphene and its Dirac Theory
Publisher Summary Graphene is an extended two-dimensional (2D) sheet of carbon atoms bound by strong nearest neighbor sp2 bonds and ordered in the form of a 2D honeycomb lattice. Stacked sheets ofExpand
Experimental studies of the electronic structure of graphene

Ultraflat graphene
TLDR
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. Expand
Free-standing graphene at atomic resolution.
TLDR
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. Expand
Thermal stability of graphene edge structure and graphene nanoflakes.
TLDR
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. Expand
Properties of graphene: a theoretical perspective

Intrinsic ripples in graphene.
TLDR
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. Expand
