Electronic Structure, Bonding, and Lithium Migration Effects of the Mixed Conductor β - LiAl

Gun-Eik Jang,I.M. Curelaru


Detailed experimental studies of the electronic structure of the valence and conduction bands of the mixed conductor β-LiAl indicate that a quasi-gap opens at the Fermi level, and the conduction states are highly localized, as opposed to the theoretical band structure calculations that predict predominant metallic behavior. Evidence for complex lithium migration effects involving the surface of LiAl, induced by particle (electron or ion) bombardment and mechanical treatment, has been obtained as a byproduct of these experiments.
