Electronic structure and transport in liquid Te

Abstract

In this paper we explore the consequence of bonding inhomogeneities on the structural, magnetic, and electrical transport properties of liquid Te in the temperature range 675-1250 K. Assuming that the short correlation length $b$ is of the order of several interatomic separations, local electronic structure and local response functions are defined. The volume fraction $C$ of the metallic regions was determined from Knight-shift data. The enhancement factor for the spin-lattice relaxation rate is proportional to $C^{-1\mathrm{}}$, in good agreement with the experimental data. The electrical conductivity and the Hall coefficient were analyzed in terms of an effective-medium theory.
