ORNL Review
Story Tip
This is a story idea from the Department of Energy’s Oak Ridge
National Laboratory. To arrange for an interview with a researcher,
please contact the Communications and External Relations staff
member identified at the end of the tip.
Atom-by-atom studies of a two-dimensional hybrid material at Oak
Ridge National Laboratory are paving the way toward novel low-power
electronics. ORNL researchers used electron microscopy to examine
newly synthesized samples of a combination of graphene and
molybdenum disulfide, which could one day form the backbone of new
electronic devices such as flexible cell phones. “In the future, it
could be possible to imprint flexible electronic circuits using
graphene and two-dimensional semiconductors such as molybdenum
disulfide,” said ORNL’s Juan-Carlos Idrobo, a co-author on the
team’s study in Nano Letters. “But first, we need to understand how
the atomic layers in these 2-D hybrid materials grow with respect
to each other before we can start to make devices out of them.”
Microscopic analysis showed that atoms in the two materials are
locked in a nonrandom orientation that is favorable for potential
electronic applications.
