The Southern Ocean, circling the Earth between Antarctica and the southernmost regions of Africa, South America, and Australia, is notorious for its High Nutrient, Low Chlorophyl zones, areas otherwise rich in nutrients but poor in essential iron. Sea life is less abundant in these regions because the growth of phytoplankton, the marine plants that form [...]
Beyond the High-Speed Hard Drive: Topological Insulators Open a Path to Room-Temperature Spintronics
Berkeley Lab theorists and experimenters have led in the exploration of the unique properties of topological insulators, where electrons may flow on the surface without resistance but with their spin orientations and directions intimately related. Recent research at beamline 12.0.1 of the Advanced Light Source opens the way to exciting prospects for practical new spintronic devices that exploit control of electron spin as well as charge.
