IBM carbon nanotube breakthrough could bring faster, smaller chips

Researchers at IBM say they've made a major breakthrough in carbon nanotube technology that could speed the development of smaller, more powerful chips.The team has figured out a way to connect carbon nanotubes -- tiny, conducting tubes of carbon atoms -- with silicon transistors in such a way that the size of the connection doesn't adversely affect its electrical properties.Shrinking the size of transistors and their associated circuitry is vital if chip technology is going to follow Moore's La
