Graphene, the extraordinary form of carbon that consists of a single
layer of carbon atoms, has produced another in a long list of
experimental surprises. In the current issue of the journal Science,
a multi-institutional team of researchers headed by Michael Crommie, a
faculty senior scientist in the Materials Sciences Division at the U.S.
Department of Energy’s Lawrence Berkeley National Laboratory and a
professor of physics at the University of California at Berkeley,
reports the creation of pseudo-magnetic fields far stronger than the
strongest magnetic fields ever sustained in a laboratory – just by
putting the right kind of strain onto a patch of graphene.
“We have shown experimentally that when graphene is stretched to form
nanobubbles on a platinum substrate, electrons behave as if they were
subject to magnetic fields in excess of 300 tesla, even though no
magnetic field has actually been applied,” says Crommie. “This is a
completely new physical effect that has no counterpart in any other
condensed matter system.”
