Static structure factors, S(q), thermodynamic properties and shear viscosities for liquid Zn, Cd, Hg, In, Tl, Sn, Pb, Sb, and Bi are investigated systematically. A model pseudotential which combines the sp‐ and d‐band contributions is employed to derive interionic interactions. The liquid state is described by using the thermodynamically self‐consistent variational modified hypernetted chain (VMHNC) integral equation theory, and also by using the linearised version of the Weeks‐Chandler‐Andersen (LWCA) thermodynamic perturbation theory of liquids. Results of calculations for all of the above properties are found to be in good agreement with available experimental data. The calculated results also reveal qualitatively that there is a relationship between the rate of change of viscosity with temperature and the depth of the potential well concerned.
PACS: 72.15.Jf; 72.15.Lh; 72.15.Cz Electronic transport properties, namely the electrical resistivity and the thermoelectric power, of liquid less-simple metals, Zn, Cd, Hg, In, Tl, Sn, Pb, Sb, and Bi, are calculated using Ziman's theory. The effective electron-ion and ion-ion interactions are described by the Bretonnet-Silbert model. The static structure factors are evaluated by the self-consistent Variational Modified Hypernetted Chain (VMHNC) integral equation of liquids. The results for the electrical resistivity are fairly good when compared with experimental data, but the agreement improves significantly when the blurring of the Fermi surface due to the finite electron mean free path is accounted for. The values of the thermoelectric power, for most systems, have the same sign and order of magnitude as the experimental ones. The results for the thermopower also show that the contribution of the energy dependent term of the electron-ion potential is significant for the concerned systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
