Nailing Down The Exciton In LiF

 

September 17, 2008

 

Exitons are a key element in the functioning of semiconductors and insulators, and understanding their structure and how they form and behave in different materials is vitally important to the development of new materials and technologies. Work at ChemMatCARS has helped settle a 70-year-old controversy about the true nature of the exciton in alkali halide insulators, the type of material in which excitons were first observed.
