Description
The recent discovery of graphene, a one-atom thick
membrane of crystalline Carbon, has opened an
extraordinary arena for new physics and applications
stemming from charge carriers that are governed by
quantum-relativistic dynamics. I will review the physical
properties of this material and present recent experimental
results obtained with scanning tunneling microscopy and
magneto-transport which provided access to the unusual
charge carriers in graphene. The findings include direct
observation of the Landau level energy spectrum that
governs the motion of the relativistic charge carriers in a
magnetic field, observation of the fractional quantum Hall
effect and a magnetically induced insulating phase.
