Penn physicists develop scalable method for making graphene
Date:3/2/2011

PHILADELPHIA New research from the University of Pennsylvania demonstrates a more consistent and cost-effective method for making graphene, the atomic-scale material that has promising applications in a variety of fields, and was the subject of the 2010 Nobel Prize in Physics.

As explained in a recently published study, a Penn research team was able to create high-quality graphene that is just a single atom thick over 95% of its area, using readily available materials and manufacturing processes that can be scaled up to industrial levels.

"I'm aware of reports of about 90%, so this research is pushing it closer to the ultimate goal, which is 100%," said the study's principal investigator, A.T. Charlie Johnson, professor of physics. "We have a vision of a fully industrial process."

Other team members on the project included postdoctoral fellows Zhengtang Luo and Brett Goldsmith, graduate students Ye Lu and Luke Somers and undergraduate students Daniel Singer and Matthew Berck, all of Penn's Department of Physics and Astronomy in the School of Arts and Sciences.

The group's findings were published on Feb. 10 in the journal Chemistry of Materials.

Graphene is a chicken-wire-like lattice of carbon atoms arranged in thin sheets a single atomic layer thick. Its unique physical properties, including unbeatable electrical conductivity, could lead to major advances in solar power, energy storage, computer memory and a host of other technologies. But complicated manufacturing processes and often-unpredictable results currently hamper graphene's widespread adoption.

Producing graphene at industrial scales isn't inhibited by the high cost or rarity of natural resources a small amount of graphene is likely made every time a pencil is used but rather the ability to make meaningful quantities with consistent thinness.

One of the more promising manufacturing techniques is CVD, or chemical vapor deposi
