Physicists Make Perpetual Clock With 4 Dimensional Crystals
2012-09-25 11:27:44

Alan McStravick for redOrbit.com - Your Universe Online Theoretical Physics made a huge leap from concept to reality yesterday thanks to collaboration between an international team of scientists and researchers with the U.S. Department of Energy´s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab). The team has proposed the experimental design of a space-time crystal that is based on an electric-field ion trap and the Coulomb repulsion of particles that carry...

3D Electrons Viewed At High Speed
2012-09-18 13:57:25

Lee Rannals for redOrbit.com - Your Universe Online A team of researchers at MIT are trying to unlock the mysteries of a promising material for future electronic devices. Scientists have managed to create three-dimensional "movies" of electron behavior in a topological insulator (TI), which were first discovered a few years ago. TIs are considered to hold great promise for new kinds of electronic devices, and having a better understanding of the unusual behavior within the material...

Might it one day be possible to transmit electricity from an offshore wind turbine to land-based users without any loss of current? Materials known as "high temperature" superconductors (even though they must be maintained at -140°C!), which can conduct electricity without any losses, were supposed to make this dream a reality. But over the past twenty-five years, scientists have not been able to make any progress in this area. Research being done in EPFL's Laboratory for Quantum...

A High-Speed Digital Storage Called Spintronics
2012-08-29 14:54:30

April Flowers for redOrbit.com - Your Universe Online The next generation of high-speed digital devices might be just a spin away. Every generation of digital electronics is smaller than the one before. Miniaturization is the way of the world, with each successive round of circuitry requiring less space and energy to perform the same tasks. No matter how small or how fast they get, today's digital technology has a functional limit. Magnetically stored digital information becomes...

Realization of a new type of magnetic phase in devices opens the door to electronics based on topologically non-trivial materials A team of researchers at RIKEN and the University of Tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission. The surprise is that their methodology for solving this classic energy problem is based upon the first realization of a highly exotic type of magnetic semiconductor first theorized less than a decade ago - a...

Avoiding Traps In Plastic Electronics
2012-07-30 09:01:59

Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw: the electronic current is influenced by "charge traps" in the material. These traps, which have a negative impact on plastic light-emitting diodes and solar cells, are poorly understood. However, a new study by a team of researchers from the University of Groningen and the Georgia Institute of Technology reveals a common mechanism underlying these traps and provides a...

Scientists from the UK's National Physical Laboratory have developed a nano-device which could change the way we define electrical current A team of scientists at the National Physical Laboratory (NPL) and University of Cambridge has made a significant advance in using nano-devices to create accurate electrical currents. Electrical current is composed of billions and billions of tiny particles called electrons. NPL scientists have developed an electron pump — a nano-device —...

Researchers who are studying a new magnetic effect that converts heat to electricity have discovered how to amplify it a thousand times over - a first step in making the technology more practical. In the so-called spin Seebeck effect, the spin of electrons creates a current in magnetic materials, which is detected as a voltage in an adjacent metal. Ohio State University researchers have figured out how to create a similar effect in a non-magnetic semiconductor while producing more...
