Faster Computers

"A one-atom-thick layer of carbon may one day help International Business Machines Corp. (IBM) and the US military build more precise radar and computers that operate at near the speed of light." Physicists "at the University of Manchester in the UK, have found a way to manipulate how graphene, the thinnest and toughest material ever produced, conducts electricity, a breakthrough that opens the door to its use in digital electronics. Because graphene conducts electricity 30 times faster than silicon -- approaching the speed of light, according to the researchers -- the finding may be used by companies such as IBM to speed up computers."
