Computer power boost as single-atom transistor built

Researchers from Australia and Finland have succeeded in building a working transistor, whose active region composes only of a single phosphorus atom in silicon.

Researchers from Helsinki University of Technology (Finland), University of New South Wales (Australia), and University of Melbourne (Australia). The results have just been published in Nano Letters (“Transport Spectroscopy of Single Phosphorus Donors in a Silicon Nanoscale Transistor”).

The rapid development of computers, which created the present information society, has been mainly based on the reduction of the size of transistors.  This also has implications for the development of quantum computers.
