Electrical Transport Properties of Liquid Ga at Different Temperatures

The electrical resistivity of metallic liquid Gallium has been calculated at different temperatures using the self-consistent approach. Most celebrated Ziman formula does not take account the blurring effect of the Fermi surface at high temperatures. So, our purpose has been to show that the self-consistent resistivity formula with temperature dependent pair potential, which takes account of blurring effect, gives better results than the simple Ziman equation under the same assumptions. As the input pseudopotential, the potential proposed by Hasegawa et al was used for full electronion interaction, which is valid for all electrons. To evaluate the temperature dependence of structure factor is described by temperature dependent potential parameter in the pair potential. Finally, the calculation of the thermal conductivity and thermo-electric power is straight forward. Same trend of resistivity with experimental data is observed, which confirms the proposed scheme for fitting the potential parameter.
