Graphene has been described as a carbon nanotube unrolled. Its two-dimensional sheet is made up of a single layer of carbon atoms arranged in a hexagonal pattern like a honeycomb. Electrons can move ballistically through these sheets even at room temperature, making graphene a prime target of the electronics industry. image from Science@Berkeley LabFrom McClatchy News/Yahoo News:
WASHINGTON — Imagine a carbon sheet that's only one atom thick but is stronger than diamond and conducts electricity 100 times faster than the silicon in computer chips.
That's graphene, the latest wonder material coming out of science laboratories around the world. It's creating tremendous buzz among physicists, chemists and electronic engineers.
"It is the thinnest known material in the universe, and the strongest ever measured," Andre Geim , a physicist at the University of Manchester, England , wrote in the June 19 issue of the journal Science.
