Electrical Properties of Semiconducting Liquid Te with Transition Metal Solutes

Abstract

The effect of localized d electrons in liquid Te has been examined. The change of electrical resistivity by addition of solute into liquid Te is positive for the “less than half” transition metal solutes and is negative for the “more than half” ones. The additional resistivity is sufficiently explained from the effects due to the s-d resonant scattering and the change of density of states at the Fermi level. This pattern of additional resistivities in the series of transition metal solutes agrees roughly with a sine function of the number of the localized d electrons.
