Single Atom Quantum Dots Bring Real Devices Closer

February 4, 2009 | Source: PhysOrg.com

Scientists at Edmonton’s National Institute for Nanotechnology have invented quantum dots less than a nanometer in diameter and containing only one atom of silicon.

By controlling electrons at a smaller scale than transistors, the quantum dots could allow for silicon-based computers 1,000 times smaller in size and with a 1,000-times reduction in power consumption.
