Diamonds Help Speed Up Spintronics
2014-03-26 04:49:49

Lee Rannals for redOrbit.com - Your Universe Online Researchers from Ohio State University have demonstrated for the first time that information can flow through a diamond wire. Scientists are working to develop “spintronics” in order to make computers simultaneously faster and more powerful. Spin could be used to help transmit data in computer circuits, and the latest research shows just how viable of an option diamonds could be. The team wrote in the journal Nature...

University of Wisconsin - Milwaukee Research finds a new way to control topological insulators Research into a recently discovered class of materials shows they have the necessary characteristics to develop ultra-energy efficient electronics. Topological insulators (TI) are three-dimensional materials that conduct electricity on their surfaces, while the interior insulates. Their surfaces are particularly unique because the motion of the electrons is "protected" by symmetry, meaning...

Johannes Gutenberg University Mainz The research group of Professor Jairo Sinova at the Institute of Physics at Johannes Gutenberg University Mainz (JGU), in collaboration with researchers from Prague, Cambridge, and Nottingham, have predicted and discovered a new physical phenomenon that allows to manipulate the state of a magnet by electric signals. Current technologies for writing, storing, and reading information are either charge-based or spin-based. Semiconductor flash or random...

Florian Aigner, Vienna University of Technology Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune their properties. An important breakthrough has now been achieved at the Vienna University of Technology: a two dimensional electron gas was created in strontium titanate. In a thin layer just...

Physicists Discover 'Quantum Droplet' In Semiconductor
2014-02-27 14:31:14

National Institute of Standards and Technology (NIST) JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet. Quasiparticles are composites of smaller particles that can be created inside solid materials and act together in a predictable way. A simple example is the exciton, a pairing, due to electrostatic forces, of an electron and a so-called...

Ion Beams Used To Create New Kinds Of Valves For Use In Spintronics
2014-02-19 10:26:38

Helmholtz-Zentrum Dresden-Rossendorf (HZDR) Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have tested a new approach to fabricating spin valves. Using ion beams, the researchers have succeeded in structuring an iron aluminium alloy in such a way as to subdivide the material into individually magnetizable regions at the nanometer scale. The prepared alloy is thus able to function as a spin valve, which is of great interest as a candidate component for use in spintronics....

Scientists Find New Path To Loss-Free Electricity
2014-02-14 12:49:57

Brookhaven National Laboratory Brookhaven Lab researchers captured the distribution of multiple orbital electrons to help explain the emergence of superconductivity in iron-based materials Armed with just the right atomic arrangements, superconductors allow electricity to flow without loss and radically enhance energy generation, delivery, and storage. Scientists tweak these superconductor recipes by swapping out elements or manipulating the valence electrons in an atom's outermost...

What's so 'super' about this superfluid Atomtronics is an emerging technology whereby physicists use ensembles of atoms to build analogs to electronic circuit elements. Modern electronics relies on utilizing the charge properties of the electron. Using lasers and magnetic fields, atomic systems can be engineered to have behavior analogous to that of electrons, making them an exciting platform for studying and generating alternatives to charge-based electronics. Using a superfluid...

Topological insulators could exist in 6 new types not seen before Topological insulators — materials whose surfaces can freely conduct electrons even though their interiors are electrical insulators — have been of great interest to physicists in recent years because of unusual properties that may provide insights into quantum physics. But most analysis of such materials has had to rely on highly simplified models. Now, a team of researchers at MIT has performed a more detailed...

Researchers Find Clear Evidence For Coherent Phonons In Superlattices
2014-02-06 13:20:27

Berkeley Lab We all learn in high school science about the dual nature of light – that it exists as both waves and quantum particles called photons. It is this duality of light that enables the coherent transport of photons in lasers. Sound at the atomic-scale has the same dual nature, existing as both waves and quasi-particles known as phonons. Does this duality allow for phonon-based lasers? Some theorists say yes, but the point has been argued for years. Recently a large...
