A team of researchers from Peking University in Beijing, China, and Duke University in Durham, North Carolina, has demonstrated that carbon nanotube-based integrated circuits can work under a supply voltage much lower than that used in conventional silicon integrated circuits.
Low supply voltage circuits produce less heat, which is a key limiting factor for increased circuit density. Carbon-based electronics have attracted attention mostly because of their speed.
The new research shows that carbon nanotube integrated circuits could also offer the promise of extending Moore's Law by allowing even more transistors to fit onto a single chip without overheating.
The results are reported in a paper accepted for publication in the American Institute of Physics' journal Applied Physics Letters.

Graphene is a tunable plasmonic medium
San Diego CA (SPX) Jun 26, 2012
With a beam of infrared light, scientists have sent ripples of electrons along the surface of graphene and demonstrated that they can control the length and height of these oscillations, called plasmons, using a simple electrical circuit. This is the first time anyone has observed plasmons on graphene, sheets of carbon just one atom thick with a host of intriguing physical properties, and an imp ... read more
