Rice University physicists find reversible way to alter VO2“²s unique electronic about-face If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you´ve never heard of. It´s a metal. It´s an insulator. It´s a window coating and an optical switch. And thanks to a new study by physicists at Rice University, scientists have a new way to reversibly alter VO2“²s electronic properties by treating it with one of the...

Berkeley Lab researchers and their colleagues demonstrate unique new materials for innovative electronic and magnetic applications Strange new materials experimentally identified just a few years ago are now driving research in condensed-matter physics around the world. First theorized and then discovered by researchers at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) and their colleagues in other institutions, these “strong 3-D topological...

As a result of a joint intensive work of several groups from five different countries, including Basque Country, a new wide class of topological insulators –materials that are insulators  in the bulk but conductors at the surface– with technologically very promising properties has been discovered. Topological insulators, first observed in 2007, are materials that, while being an insulator inside or in the bulk, behave as metals at the surface. Their unique properties can...

A Duke University team has seen for the first time how soft polymers, such as wire insulation, can break down under exposure to electrical current.Researchers have known for decades that polymers, such those insulating wires, may break down due to deformation of the polymers. But the process had never been seen.In a series of experiments, Duke University engineers have documented at the microscopic level how plastic deforms to breakdown as it is subjected to ever-increasing electric voltage....
