[ Watch The Video: Atomic Quantum Dot Based Quantum Cellular Automata ] By Bryan Alary, University of Alberta UAlberta research team developing atom-scale, ultra-low-power computing devices to replace transistor circuits. In the drive to get small, Robert Wolkow and his lab at the University of Alberta are taking giant steps forward. The digital age has resulted in a succession of smaller, cleaner and less power-hungry technologies since the days the personal computer fit...

University of Innsbruck One of the most remarkable consequences of the rules in quantum mechanics is the capability of a quantum particle to penetrate through a potential barrier even though its energy would not allow for the corresponding classical trajectory. This is known as the quantum tunnel effect and manifests itself in a multitude of well-known phenomena. For example, it explains nuclear radioactive decay, fusion reactions in the interior of stars, and electron transport through...

Researchers in the College of Engineering at Oregon State University have made a significant advance in the function of metal-insulator-metal, or MIM diodes, a technology premised on the assumption that the speed of electrons moving through silicon is simply too slow. For the extraordinary speed envisioned in some future electronics applications, these innovative diodes solve problems that would not be possible with silicon-based materials as a limiting factor. The new diodes consist of...

Early results using novel materials and processes achieves milestone toward low-power tunnel transistor electronics Researchers at Rochester Institute of Technology, international semiconductor consortium SEMATECH and Texas State University have demonstrated that use of new methods and materials for building integrated circuits can reduce power–extending battery life to 10 times longer for mobile applications compared to conventional transistors. The key to the breakthrough is a...

New work suggests constructing novel particle opens the door to taming the mysteries of quantum tunneling Scientists at the Cavendish Laboratory in Cambridge have used light to help push electrons through a classically impenetrable barrier. While quantum tunneling is at the heart of the peculiar wave nature of particles, this is the first time that it has been controlled by light. Their research is published today, 05 April, in the journal Science. Particles cannot normally pass through...

A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling.Physics professors Alexey Bezryadin and Paul Goldbart led the team, with graduate student Mitrabhanu Sahu...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
