Electrical transport properties of some liquid metals

Abstract

In the present article, we report the electrical transport properties viz. the electrical resistivity (ρ), the thermoelectric power and thermal conductivity (σ) of several monovalent, divalent and polyvalent liquid metals of the different groups of the periodic table on the basis of model potential formalism. The well-known empty core model potential of Ashcroft is used for the first time with seven local field correction functions proposed by Hartree, Hubbard–Sham, Vashishta–Singwi, Taylor, Ichimaru–Utsumi, Farid et al. and Sarkar et al. in the present computation and found suitable for such study. In the calculation of these properties we have used the values of the theoretical structure factors due to hard core fluid theory. It is concluded that the comparisons of present and theoretical or experimental findings wherever exists are highly encouraging.
