The electronic properties of graphene allow a population inversion to be established within the duration of a 35-femtosecond light pulse.

Photoemission performed with circular polarized light can detect the chirality of electronic wave functions in single- and double-layer graphene.

Graphene, a single layer of carbon atoms, can be multiply folded in a controlled way into various types of single or periodic structures with intriguing properties.

A line defect that seems to naturally form in graphene grown on a nickel substrate may provide additional control of transport characteristics.

Tuning the area of the Fermi surface of graphene demonstrates the fundamental physics of electron-phonon scattering.

The same organic molecule that proved successful as an electron acceptor in light emitting diodes may be a technologically viable material for doping graphene.

A very high magnetic field splits the zero-energy Landau level of bilayer graphene revealing eight distinct levels.

Calculations of bilayer graphene reveal the possibility of new electronic phases.

Due to unusual spinlike properties, electrons in graphene—despite scattering—exhibit a small increase in their conductivity.

Photoelectron spectroscopy reveals how carbon atoms aggregate to form domelike graphene structures on iridium surfaces.

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

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.

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.
