Carbon nanotubes fit by the thousands onto a chip

[Gerald]

Scientists have demonstrated methods that could see higher-performance computer chips made from tiny straws of carbon called nanotubes.

Carbon nanotubes have long been known to have electronic properties superior to current silicon-based devices.

But difficulties in manipulating them have hampered nanotube-based chips.

The experiments, reported in Nature Nanotechnology, show a kind of two-part epoxy approach to individually place the nanotubes at high density.The race is on in the semiconductor chip industry to replace current silicon technology - methods to make smaller and therefore faster devices will soon come up against physical limits on just how small a silicon device can be.

Study co-author James Hannon, a materials scientist at IBM, said that there are few realistic successors to silicon's throne.

There are several materials you can use to make chips, but I don't think they are cost effective.

They want to use the same materials to build a "space elevator"

I hate to use wikipedia, but the article explains it very well.
