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

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

Highly doped graphene can become superconducting.

Transport characteristics of graphene nanoribbons have implications for nanodevices.

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.

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

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

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

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.
