A controllable transistor engineered from a single phosphorus atom shown here in the center of an image from a computer model, sits in a channel in a silicon crystal.
The smallest transistor ever built — in fact, the smallest transistor that can be built — has been created using a single phosphorus atom by an international team of researchers at the University of New South Wales, Purdue University and the University of Melbourne.
The single-atom device was described Sunday (Feb. 19) in a paper in the journal Nature Nanotechnology.
Michelle Simmons, group leader and director of the ARC Centre for Quantum Computation and Communication at the University of New South Wales, says the development is less about improving current technology than building future tech…
