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...

With the Advanced Light Source Berkeley Lab scientists explore the electronic structure of graphene in regions never before tested by experiment Graphene, a sheet of carbon only a single atom thick, was an object of theoretical speculation long before it was actually made. Theory predicts extraordinary properties for graphene, but testing the predictions against experimental results is often challenging. Now researchers using the Advanced Light Source (ALS) at the U.S. Department of Energy's...

Paul Preuss, Berkeley Lab Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). Different colors have different energies, and no single semiconductor has a band gap that can respond to sunlight's full range, from low-energy infrared through visible light to high-energy ultraviolet. Although full-spectrum solar cells have been made, none yet have been suitable for manufacture at a consumer-friendly price. Now Wladek...
