Nailing Down the Exciton in LiF
September 17, 2008
Excitons are a key element in the functioning of semiconductors and insulators. Understanding their structure and behavior is vitally important to the development of new materials and technologies. Research by experimenters using two beamlines at the U.S. Department of Energy’s Argonne Advanced Photon Source could set the stage for improving materials used for alternative energy sources, while settling a 70-year-old controversy.
