Turning Light Into Matter: Scientists Say 80-Year-Old Theory Is Provable
2014-05-19 08:30:22

Lawrence LeBlond for redOrbit.com - Your Universe Online First theorized in 1934 by a pair of scientists – Gregory Breit and John Wheeler – turning light into matter was deemed a fantastical and equally impossible feat. By smashing two photons together at a high rate of speed, the scientists hypothesized that it could create an electron and a positron. An occurrence of such magnitude was deemed extremely rare and difficult to reproduce. So rare that it has never been observed in any...

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...

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the University of Exeter have reportedly developed a new flexible and transparent photoelectric device that converts light into electrical signals by taking advantage of a pair of recently discovered materials. The device, which is detailed in the latest edition of the journal ACS Nano, exploits the unique properties of graphene, the thinnest conductive material on Earth, and graphExeter, the best-known room...

Surprising Control Over Photoelectrons From A Topological Insulator
2013-03-13 15:22:44

Lawrence Berkeley National Laboratory Berkeley Lab scientists discover how a photon beam can flip the spin polarization of electrons emitted from an exciting new material Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in the bulk, yet behaves like a metal on its surface. Researchers find TIs exciting partly because the electrons...

Ability to probe deep below material surfaces should be boon for nanoscale devices The expression "beauty's only skin-deep" has often been applied to the chemistry of materials because so much action takes place at the surface. However, for many of the materials in today's high technologies, such as semiconductors and superconductors, once a device is fabricated it is the electronic structures below the surface, in the bulk of the material or in buried layers, that determine its...

Scientists can now look deeper into new materials to study their structure and behavior, thanks to work by an international group of researchers led by UC Davis and the Lawrence Berkeley National Laboratory and published Aug. 14 by the journal Nature Materials. The technique will enable more detailed study of new types of materials for use in electronics, energy production, chemistry and other applications. The technique, called angle-resolved photoemission, has been used since the 1970s to...
