Researchers pinpoint graphene's varying conductivity levels
Date:4/18/2011

With the help of the high performance computers at Oak Ridge National Laboratories, the NC State team discovered both good and bad news about graphene. Their results appear as an Editor's Suggestion in the April 15 edition of Physical Review B.

With a single layer of graphene, the mobility and therefore conductivity shown by the researchers' simulations turned out to be much higher than they had originally thought. This good news was balanced, however, by the results from the bilayer state.

"We expected that the electrons' conductivity in bilayer graphene could be somewhat worse, due to the ways in which the vibrations from the atoms in each individual layer interact with one another," Mullen says. "Surprisingly, we found that the mobility of electrons in bilayer graphene is roughly an order of magnitude lower than in a single graphene sheet."

"The reduction is substantial, but even this reduced number is higher than in many conventional semiconductors," Borysenko adds.

Buongiorno-Nardelli says that the NC State researchers are turning their attention to remedying this problem.

"If we put the graphene on a substrate that can 'siphon off' some of the heat generated by the electric current, the crystal vibrations will decrease and the mobility will increase. Those are our next steps running the simulations with graphene and substrates that have this property."
