Nanotubes grown on wafer

from the bridging-small-gaps dept.
Nanotubes grown in place, an article by Eric Smalley in Technology Research News, reports the accomplishment of Stanford University researchers in growing individual carbon nanotubes directly between pairs of electrodes formed on a silicon wafer using photolithography. "The resulting nanotubes were 2.5 nanometers in diameter and spanned electrode gaps ranging from 3,000 to 10,000 nanometers." Anticipated applications include use in sensors, electromechanical transducers, and high frequency mechanical resonators. The research was published in the July 29, 2002 issue of Applied Physics Letters.
