An international team at the University of New South Wales, Purdue University and the University of Melbourne, has described the smallest transistor ever built in the 'Nature Nanotechnology' journal.
Michelle Simmons, who led the team, says the development is less about improving current technology than building future technology.
"This is a beautiful demonstration of controlling matter at the atomic scale to make a real device. Fifty years ago when the first transistor was developed, no one could have predicted the role computers would play in our society today.
"As we transition to atomic-scale devices, we are now entering a new paradigm where quantum mechanics promises a similar technological disruption. It is the promise of this future technology that makes this present development so exciting," Simmons said.
A single phosphorus atom is just 0.1 nanometres across, which would significantly reduce the size of processors made using this technique, although it may be many years before single-atom processors actually are manufactured.
