A new eletronic revolution?

Nonatechelogy is photonic (photon-based computing) or quantum eletronic, and research and speculation grow, 
but a research on carbon nanotubes and graphene (a compound made up of nanotubes) is faster than practical results directly applicable to today’s computing and is possible change it.
Current computing uses a technology that uses tiny links using metallic oxide over silicon (or CMOS – Complementary Metal Oxide Semiconductor) to achieve non-zero-order operations (10-9 seconds) by placing micro-transistors on a scale of non-meters (10 -9 of the second) this has limited the advance of computer chips as this is a maximum barrier for such technology.
Now researchers at Peking University in China say they have found a way to put transistors based on carbon nonotube technology that far outnumber these made with metal-oxide-based technology on silicon, the transistors are much smaller in the femtomeconds ( 10-15) built in silicon on scales below nanometers.
Unlike the conventional techniques of growing carbon nanotubes in silicon, which had many undesirable properties, they placed only a few nanotubes and tested the properties made on tiny sheets of graphene (methods to construct by processes similar to revealing photos in very microscopic structures of Transistors), and obtained excellent results.
The gates that make the operations come to operate thanks to the capacitance of these new structures in the femtoseconds, which guarantees a speed a thousand times faster than the current technologies of silicon chips.
More than that, traders say their work provides physical evidence that all the money spent on carbon nanotube research as a substitute for current silicon technologies will be paid when mass production of these chips is made viable.
The article is published in phy.org which is a journal specializing in nanotechnology work.
