Scientists Attain Control of How Electrons Move Through a Nano-Transistor

Today, all electronics are based on transistors. Danish scientists are leading the field in creating the smallest transistors (called nano-transistors).

Two physicists from the Nano-Science Centre at the University of Copenhagen have now attained unsurpassed control of the migration of electrons in a nano-transistor. By using quantum physics, the scientists have made the electrons ‘communicate’ with each other.

In a recent experiment, carried out at temperatures near absolute zero, the scientists show how electrons, through their so-called spin, establish a quantum mechanic cohesion and thereby help each other through the molecule in the nano-transistor.

This achievement is not only a breakthrough in the fundamental research of nanotechnology; it also influences the development of tomorrow’s electronics, e.g. future super-fast quantum-computers.

The result is attained through an international collaboration with physicists from Harvard University and Universität Karlsruhe, and was published in Nature Physics on the 4th of July 2006.
