Production of dramatically smaller, faster, more powerful computer chips–and that means smaller, faster, more powerful computers–is closer to reality as the result of an advance in carbon nanotube transistor fabrication at IBM. For the first time, more than ten thousand functioning transistors made of nano-sized tubes of carbon have been precisely placed and tested in a single chip using standard semiconductor processes. Carbon nanotubes are a new class of semiconductor materials. Their electrical properties allow electrons to move easier and faster than conventional silicon devices. Nanotubes are also the ideal shape for transistors at the atomic scale. The combination of unique […]
