Abstract

To cite this article: Aditya M. Vora (2011) Study of electrical transport properties of liquid semiconductor binary alloys using pseudopotential theory,The electrical transport properties, namely, the electrical resistivity (), the thermoelectric power and thermal conductivity () of several polyvalent semiconductor binary alloys, namely, Cd 1 À X Sn X , Cd 1 À X Pb X and Cd 1 À X Bi X were calculated from the pseudopotential form factors and Percus-Yevick (PY) hard sphere structure factors of Ashcroft and Langreth. The well-recognised empty core model potential of Ashcroft is used for the first time with seven local field correction functions due to Hartree (H), Hubbard-Sham (HS), Vashishta-Singwi (VS), Taylor (T), Ichimaru-Utsumi (IU), Farid et al. (F) and Sarkar et al. (S) in the present computation and found suitable for such a study. It is concluded that the comparison of present and experimental findings is highly encouraging.

Pseudopotential-based study of electrical transport properties inherent to Bi-Ga alloys

“…The FZ model is used for calculating the electrical resistivity of Bi-Ga alloy [1][2][3][4][5][6][7][8],…”

“…The properties of electronic materials and interfaces between electronic materials are used to elucidate behavior of a variety of semiconductor devices, namely: solid-state lasers, light emitting diodes, bipolar transistors, sensors and field effect transistors etc. Therefore, to understand the electronic structure of the semiconductor materials, the electronic transport properties play an important role and show fascinating interest for research community [1][2][3][4][5][6][7][8]. The electronic transport properties of liquids can be extensively described by the simple model suggested by Faber and Ziman (FZ) [4].…”

Electrical Transport Properties of K-Based Alkali Liquid Binary Alloys

“…Now assuming the free-electron distribution, an expression for the electrical resistivity of liquid metal in terms of the average of the product of the structure factor and pseudopotential matrix element can be written as, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]21] …”

“…And hence the study of electrical transport properties of liquid metals and their alloys remain one of the favourite quantities either experimentally or theoretically. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] It was found that the electrical resistivities of the alloys obey two rules: (i) Nordheim's rule [19] and (ii) Linde's rule. [20] In the Nordheim's rule the resistivity of liquid alloys depends directly on the product of the atomic concentrations in the percentage of the guest and host elements.…”

Effect of Ce on resistivity of Sn-3.8Ag-0.7Cu-xCe lead-free solders

“…Over the past decades, much attention has been paid to the research of liquid-liquid structure transition (L-LST) and resistivity of liquids. [6][7][8][9][10][11] Considerable investigations reveal or indicate the existence of the L-LSTs with reversible or irreversible characters in many liquid metals and alloys. [12][13][14][15][16] Many researchers focus on the microstructure and properties of lead-free solder; however, little attention has been paid to the liquid properties of lead-free solder.…”
