LED material shines under strain

Smartphones, laptops, and lighting applications rely on light-emitting diodes (LEDs) to shine bright. But the brighter these LED technologies shine, the more inefficient they become, releasing more energy as heat instead ...

Researchers predict material 'denser than diamond'

(PhysOrg.com) -- Stony Brook University graduate student Qiang Zhu, together with Professor of Geosciences and Physics, Artem R. Oganov, postdoc Andriy O. Lyakhov and their colleagues from the University de Oviedo in Spain, ...

Unlocking the secrets of spin with high-harmonic probes

Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ...

Graphene -- the copy beats the original

(PhysOrg.com) -- The first artificial graphene has been created at the NEST laboratory of the Italian Institute for the Physics of Matter (INFM-CNR) in Pisa. It is sculpted on the surface of a gallium-arsenide semiconductor, ...

A huge step toward mass production of graphene

Scientists have leaped over a major hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell ...

Carbon nanoballs as data storage units

Small, smaller, "nano" data storage! Interest is growing in the use of metallofullerenes - carbon “cages” with embedded metallic compounds - as materials for miniature data storage devices. Researchers at Empa have discovered ...

Gallium nitride transistor could replace silicon

(PhysOrg.com) -- A Cornell researcher has created an extremely efficient transistor made from gallium nitride, which may soon replace silicon as king of semiconductors for power applications.
