Researchers Have Created A Stable Two-dimensional Electron Gas In Strontium Titanate
2014-03-04 08:12:15

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...

This work was recently published in Physical Review Letters In contrast to its apparent simplicity (that brought Einstein his Nobel Prize), the photoelectric effect, when an electron is knocked out from its parent atom by a photon, is quite complicated to analyze in general, especially when the atom contains a large number of electrons. Like the many-body problem in classical mechanics, the quantum many-body problem is very difficult to conceptualize and remains a serious challenge for...

Researchers Observe High Energy Losses In Vicinity Of Charge Density Waves
2013-12-16 07:29:11

University of Basel In collaboration with the University of Basel, an international team of researchers has observed a strong energy loss caused by frictional effects in the vicinity of charge density waves. This may have practical significance in the control of nanoscale friction. The results have been published in the scientific journal Nature Materials. Friction is often seen as an adverse phenomenon that leads to wear and causes energy loss. Conversely, however, too little friction...

Researchers have made the first experimental determination of the weak charge of the proton in research carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility (Jefferson Lab). The results, accepted for publication in Physical Review Letters, also include the determinations of the weak charge of the neutron, and of the up quark and down quark. These determinations were made by combining the new data with published data from other experiments. Although these...

Carbon Capture Monitoring With Cosmic Rays
2013-09-15 04:27:27

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Durham University in the UK are looking towards the stars for a method to reduce costs associated with carbon capture and storage (CCS) – a process that could potentially mitigate contribution of fossil fuel emissions to global warming and ocean acidification. According to BBC News science reporter Simon Redfern, CCS involves capturing carbon dioxide (CO2) from fuel as it is burned at a power station. That CO2...

A pair of physicists hired to help lead particle and nuclear physics research in the new doctorate program at South Dakota School of Mines & Technology hold the promise of bringing the long-awaited Ph.D. to the world stage. Rapid City, SD (PRWEB) August 30, 2013 A pair of world-class particle physicists have been added to the South Dakota School of Mines & Technology faculty as it continues to expand with a new Ph.D. program in physics. The new doctorate program will serve the...

Flavor Changing Neutrinos
2013-08-23 13:29:53

John P. Millis, PhD for redOrbit.com - Your Universe Online Protons, neutrons, and electrons – it is these tiny particles that make up most of the normal matter (that is, non-dark matter) in the Universe. Yet it is another, nearly massless particle that may turn out to be the most revealing about the nature of the cosmos. The neutrino plays a crucial role in nuclear processes such as fusion. But because of its small mass and neutral charge, it is very difficult to measure and study...

International research including the UK and Japan has confirmed that subatomic particles called neutrinos have a new form of identity-shifting property. Announced today (19 July 2013) these results could one day help scientists explain why the universe contains matter but very little antimatter. The findings are further confirmation from the T2K neutrino experiment in Japan of neutrinos changing between different types, or oscillating, in a new way. Dr Alfons Weber, Professor of Physics...

GERDA sets new limits on extremely rare decay Neutrinos are the most elusive particles having extremely weak interactions with all other particles. They have rather unusual properties and are even expected to be identical with their own antiparticles. So far this property is, however, not experimentally verified even though many studies of neutrinos over the last 60 years have already boosted our understanding of elementary particle physics. Now scientists of the GERDA collaboration...

Antimatter Particles From Solar Flares
2013-07-10 08:32:20

John P. Millis, PhD for redOrbit.com - Your Universe Online When the Universe was born, equal amounts of matter and anti-matter - matter with the same physical behavior as its matter counterparts, but with opposite charge - should have been created. However, the cosmos now appears to be dominated by normal matter. Usually, direct study of anti-matter requires costly particle-accelerator experiments, or in some cases space-based observatories. Now however, Gregory D. Fleishman from the...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
