Article Summary

The world's narrowest silicon wires with a cross section of a mere four atoms by one atom have been created by a team of developers from the University of New South Wales, the University of Melbourne and Purdue University. The wires are fully functioning, with current-carrying capacity equivalent to that of a microprocessor's copper cable, despite being 20 times thinner - and 10,000 times narrower than a human hair.
