Crime-scene investigators may soon have a new tool to help them catch evildoers. Researchers have demonstrated the proof-of-principle for a new forensic technique to identify individual fibers of cloth, which often all look alike. "White cotton fibers are so common and have so few visual distinguishing features that they are largely ignored by forensic scientists at crime scenes," says Brian Strohmeier, a scientist at Thermo Fisher Scientific, a laboratory-instrument company based in...

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...

New theory of 'Extremely Correlated Fermi Liquids' may explain anomalous photoemission spectra of high-temperature superconductors Although high-temperature superconductors are widely used in technologies such as MRI machines, explaining the unusual properties of these materials remains an unsolved problem for theoretical physicists. Major progress in this important field has now been reported by physicists at the University of California, Santa Cruz, in a pair of papers published...
