Branching Is Key to Carbon Nanotube Transistors

by Sarah Graham ScientificAmerican.com, 15 Aug 2005 Scientists have long been intrigued by the electrical properties of carbon nanotubes, those tiny straws of pure carbon measuring less than a hair's width across. Now one research team has unveiled an improved design for transistors based on the minuscule tubes, one that could substantially reduce the lower limit on transistor size. Read more
