摘要

We present a numerical study of the electronic structure of a simple model of molten salts, with application to alkali halides. The geometry of the model is simulated using the primitive model of charged hard spheres, the electronic structure is described by a tight-binding Hamiltonian. We study the influence of the topological and Madelung potential disorder on the evolution of the density of states upon melting and the optical absorption, the latter directly comparable to experiments. A population analysis of the cationic conduction band is performed, the results are discussed with respect to the possible formation of dipolar atoms in the corresponding metal-molten salt solutions.
