Study on electronic transport properties of some bulk metallic glasses using pseudopotential theory

ABSTRACT

In the present paper, we report the electrical transport properties, namely electrical resistivity, thermoelectric power and thermal conductivity by using Shaw’s constant core model pseudopotential in conjunction with Ziman’s theory of electrical properties of some 20 bulk metallic glasses constituted by binary to hexanary metallic elements for the first time. The screening influences are studied by different exchange and correlation functions. The current fallouts of electrical resistivity are observed in qualitative nature with available experimental data.
