The full Dirac spectrum has been measured in intercalated graphite.

The mobility of charge carriers in epitaxial bilayer graphene may be limited by structural domains.

Graphene is not just your everyday relativistic quantum playground; it may have ghostly chaotic features as well.

Along with the quark gluon plasma and cold atom gasses, graphene is establishing its place as a perfect liquid.

Can a patterned semiconducting heterostructure yield a better “graphene”?

Scanning tunneling spectroscopy establishes the dominant mechanism of electron scattering when graphene is placed on a substrate.

With a high-energy electron beam, it is possible to carve out atomically thin strands of carbon. Whether these carbon structures are conducting remains an open question.

Graphene, believed to be a semimetal so far, might actually be an insulator when suspended freely.

Adding a third layer to bilayer graphene leads to a drastic modification of its electronic energy band structure.

The friction on a sharp tip sliding along a double layer of graphene is half that of a single layer. The source of the contrast may be the difference in electron-phonon coupling in the two systems.

Experiments suggest that one-dimensional behavior is reflected in the transport properties of graphene nanoribbons.

Metallic contacts, which are unavoidable in any connection to an experimental measurement, cause asymmetries in the conductance of electrons and holes in graphene.

Graphene has been idealized as a two-dimensional electron system in which the electrons behave like massless fermions, but how “perfect” is it? Scientists now show they can prepare free-standing sheets of graphene that have some of the highest electron mobilities of any inorganic semiconductor.

By adsorbing and desorbing nitrogen dioxide, it is possible to add and remove charge carriers from graphene and induce a reversible metal-insulator transition.
