Potential 100 GHz Carbon Nanotube Molecular Computer

leb writes: "Researchers at Harvard have developed "a concept for molecular electronics exploiting carbon nanotubes as both molecular device elements and molecular wires for reading and writing information. Each device element is based on a suspended, crossed nanotube geometry that leads to bistable, electrostatically switchable ON/OFF states. The device elements are naturally addressable in large arrays by the carbon nanotube molecular wires making up the devices. These reversible, bistable device elements could be used to construct nonvolatile random access memory and logic function tables at an integration level approaching 1012 elements per square centimeter and an element operation frequency in excess of 100 gigahertz." Unfortunately to read the entire article in Science Online you need a subscription, but you can still take a look at the abstract."

Scientific American just had an article much like this, which you can read here without a subscription. They did mention Buckytubes, but didn't focus on them specifically.

This article was posted in the science section and deemed "not important enough" for the main page. You can still access it through older stuff or the Science slashbox. This probably either was because of its slightly vaporous quality or because of the required subscription.

They had better hurry.

If conventional architectures are able to keep up with the standard "double in speed every 18 months", it will only take them about 10 years to hit the 100GHz mark too.

Will this technology ripen within 10 years?
