Transistors consisting of single atoms or several-atom clusters may lay the framework for future quantum computing and offer unparalleled memory and processing power.

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues at the University of Maryland have developed a step by step procedure to produce such atomic-scale transistors. They are only the second in the world to construct a single-atom transistor and to fabricate a series of single-electron transistors.
