Instrument Reveals Quartet of Graphene Electron States Atlanta
(September 7, 2010) — Using a one-of-a-kind instrument designed
and built at the National Institute of Standards and Technology
(NIST), researchers have “unveiled” a quartet of graphene’s
electron states and discovered that electrons in graphene can
split up into an unexpected and tantalizing set of energy levels
when exposed to extremely low temperatures and extremely high
magnetic fields. Reported Sept. 9 in the journal Nature, the new
research raises several intriguing questions about the
fundamental physics of this exciting material and reveals new
effects that may make graphene even more powerful than
previously expected for practical applications. Led by NIST
Fellow Joseph Stroscio, the research team included scientists
from the Georgia Institute of Technology, the University of
Maryland, Seoul National University, and the Univers
