Next-Gen Carbon Nanotube Microchips

Carbon nanotubes have long been known to have electronic properties superior to current silicon-based devices, but scientists faced difficulties in manipulating them.

The experiments, reported in Nature Nanotechnology, show that ion-exchange chemistry can be used to fabricate arrays of individually positioned carbon nanotubes, with a density two orders of magnitude higher than previous reports.

Using this method, scientists created a series of  nanotube devices at a density of a billion tubes per square centimeter.

Next-Gen Carbon Nanotube Microchips

Carbon nanotubes (CNTs):

are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1, significantly larger than for any other material. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. In particular, owing to their extraordinary thermal conductivity and mechanical and electrical properties, carbon nanotubes find applications as additives to various structural materials. For instance, nanotubes form only a tiny portion of the material(s) in (primarily carbon fiber) baseball bats, golf clubs, or car parts.
