Nanotech breakthrough - scientists attain control of how electrons move through a nano-transistor

06.07.2006
Today, all electronics are based on transistors. The smallest transistors are nano-transistors. Two physicists from the Nano-Science Centre and the Niels Bohr Institute 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 are published in Nature on the 4th of July 2006.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
