Study Identifies Path Toward Engineering Materials For Super-efficient Nanoelectronics
2014-03-20 12:14:45

DOE/SLAC National Accelerator Laboratory Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have discovered a potential way to make graphene – a single layer of carbon atoms with great promise for future electronics – superconducting, a state in which it would carry electricity with 100 percent efficiency. Researchers used a beam of intense ultraviolet light to look deep into the electronic structure of a material made of...

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...

Scientists Find New Path To Loss-Free Electricity

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...

Study Advances Quest For Better Superconducting Materials

Oak Ridge National Laboratory Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors. Their work, published in Physical Review Letters, examines the role of chemical dopants, which are essential to creating high-temperature superconductors – materials that conduct electricity without resistance. The role of dopants in superconductors is...

Universal Ripple May Hold Secret To High-temperature Superconductivity
2013-12-20 15:08:38

University of British Columbia UBC researchers have discovered a universal electronic state that controls the behavior of high-temperature superconducting copper-oxide ceramics. The work, published this week in the journal Science, reveals the universal existence of so-called 'charge-density-waves' -- static ripples formed by the self-organization of electrons in the material's normal state. These ripples carry the seeds out of which superconductivity emerges. "Our understanding of...

A measuring device for superconductors breaks world records Weizmann Institute scientists have taken a quantum leap toward understanding the phenomenon known as superconductivity: They have created the world’s smallest SQUID – a device used to measure magnetic fields – which has broken the world record for sensitivity and resolution. Superconductivity is a quantum phenomenon that only occurs when certain materials are cooled to extremely low temperatures. Then, they lose all...

X-rays Reveal Another Feature Of High-temperature Superconductivity
2013-11-25 08:20:57

European Synchrotron Radiation Facility Discovery of a giant resonance puts these materials further apart Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. As this mechanism called...

Advances in technology for computation and information storage always require to make the systems smaller and faster. The limits of miniaturization are those set by nature: Materials are composed by specific units, the atoms, that cannot be further divided. The question arising is: Can we still codify information at the atomic scale? And the answer is yes, we can! but one needs to manipulate a property of the atoms, individually, and keep them in that state there for sufficiently long time to...

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...

cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
