Every atom counts in graphene formation

Rice University lab’s nanoreactor theory could advance quality of material’s growth

HOUSTON – (Sept. 4, 2012) – Like tiny ships finding port in a storm, carbon atoms dock with the greater island ofgraphene in a predictable manner. But until recent research by scientists at Rice University, nobody had the tools to make that kind of prediction.
Electric current shoots straight across a sheet of defect-free graphene with almost no resistance, a feature that makes the material highly attractive to engineers who would use it in things like touchscreens and other electronics, said Rice theoretical physicist Boris Yakobson. He is co-author of a new paper about graphene formation to appear this week in the Proceedings of the National Academy of Sciences.
