Nanoscience takes one more step forward as the first single-molecule computer circuit was just built by United States researchers. Take a look at the picture here and you’ll see the circuit which is so tiny it measures less than a fifth of the width of a human hair. It was assembled on a single carbon nanotube, and even though it can only achieve a poky speed of 50MHz, that’s 100,000 times faster than any other devices that have ever been made with carbon nanotubes.
This proof of concept shows that it will probably be possible to use nanotech to dramatically increase processor speed, keeping Moore’s law going a few years longer.
