Electronic Structure of Lanthanum Hydrides with Switchable Optical Properties
Abstract
Recent dramatic changes in the optical properties of LaH2+x and YH2+x films discovered by Huiberts et al. suggest their electronic structure is described best by a local model. Electron correlation is important in H- -centers and in explaining the transparent insulating behavior of LaH3. The metal-insulator transition at x 0.8 takes place in a band of highly localized states centered on the H-vacancies in the LaH3 structure.
