Y Shaped Nanotubes to Offer Smaller Transisters
FormFactor
At the core of forgotten
New Scientist has an article up discussing the possibility that tiny tubes of carbon, crafted into the shape of a Y, could revolutionise the computer industry.
Prab Bandaru and colleagues at the University of California in San Diego, and Apparao Rao, of Clemson Univeristy in South Carolina added iron-titanium particles to a standard carbon nanotube to spur the growth of an extra nanotube branch attached to the main stem. The overall structure assumed a Y-shape and the catalyst particles were absorbed into the tubes at the branching point.
