Localized and mobile electrons in metal - molten-salt solutions

Abstract

At elevated temperatures (about ) liquid alkali metal - alkali halide solutions transform continuously from the nonmetallic to the metallic state (NM - M transition) as a function of the metal mole fraction . In this study we present results of new experiments on spectroscopic ellipsometry and on absorption spectroscopy across the transition regime. The data indicate that on both sides of the NM - M transition localized and mobile electronic states may coexist
