Down to the wire: Silicon links shrink to atomic scale
Date:1/5/2012

  • The narrowest conducting wires in silicon ever produced are shown to have the same electrical current carrying capability as copper, as published in Science.
  • This means electrical interconnects in silicon can be shrunk to the atomic-scale without losing their functionality Ohm's law holds true at the atomic-scale.
  • UNSW researchers will use these wires to address individual atoms a key step in realising a scalable quantum computer.

The narrowest conducting wires in silicon ever made just four atoms wide and one atom tall have been shown to have the same electrical current carrying capability of copper, according to a new study published today in the journal Science.

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.

"Interconnecting wiring of this scale will be vital for the development of future atomic-scale electronic circuits," says the lead author of the study, Bent Weber, a PhD student in the ARC Centre of Excellence for Quantum Computation and Communication Technology at the University of New South Wales, in Sydney, Australia.

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.

The researchers discovered that the electrical resistivity of their wires a measure of the ease with which electrical current can flow does not depend on the wire width. Their behaviour is described by Ohm's law, which is a fundamental law of physics taught to every high school student.

"It is extraordinary to show that such a basic law still holds even when constructing a wire from the fundamental building blocks of nature atoms,"
