Wires shrink to atomic scale

Oz Research of Note (in progress)

Sydney researcher have developed the narrowest conducting wires in silicon ever made – just four atoms wide and one atom tall – and shown them to have the same electrical current carrying capability of copper. Despite their astonishingly tiny diameter – 10,000 times thinner than a human hair – these wires have exceptionally good electrical properties, raising hopes they will serve to connect atomic-scale components in the quantum computers of tomorrow.

The wires were made by precisely placing chains of phosphorus atoms within a silicon crystal, according to the study, which includes researchers from the University of Melbourne and Purdue University in the US.
