Advances in carbon nanotubes for computing

IBM has announced today that it’s been playing around with carbon nanotubes, and has come up with a way to measure the distribution of electrical charges in tubes smaller than 2 nm across. This is an incremental step along the path toward use of carbon nanotubes as semiconductors and wires on chips.

…”The success of nanoelectronics will largely depend on the ability to prepare well characterized and reproducible nano-structures, such as carbon nanotubes,” said Dr. Phaedon Avouris, IBM Fellow and lead researcher for IBM’s carbon nanotube efforts. “Using this technique, we are now able to see and understand the local electronic behavior of individual carbon nanotubes.”
