A method for sorting nanotubes by electronic properties could make the widespread use of nanotube-based electronic devices a reality.
The use of carbon nanotubes in ultra-fast computers and other electronic devices has been hampered because parts of the material contain nanotubes with different electronic properties. One nanotube is semiconductor, while the next is conductive.
Now researchers at Northwestern University have developed a practical and reliable method of bringing order to this chaos, allowing for the precise separation of nanotubes of the types needed for high-performance electronic devices. This breakthrough could accelerate progress toward nanotube computers and has many short-term applications, including high-definition displays, nanotoxicity analysis devices, and solar cells.
