This leads to absence of single experiment technique which could produce a direct mapping of the glass network structure. To study lattice dynamical properties de Launey angular force constant method can be considered as one of the best fitted method so in this study lattice dynamical properties of Mg2Ge has been studied using de Launey angular force constant model.
Semiconducting magnesium silicide (Mg2Si) and magnesium germanide (Mg2Ge) have an antifluorite structure (space group Fm3m) and have been proposed to be good candidates for high-performance thermoelectric materials, because of their superior features such as its large Seebeck coefficient, low electrical resistivity, and low thermal conductivity To study the properties of such materials of interest various theoretical methods can be used. Solid-state physics thus forms the theoretical basis of materials science, as well as having direct applications, for example in the technology of transistors and semiconductors. Solid-state physics considers how the large-scale properties of solid materials result from their atomic-scale properties. Solid-state physics, the largest branch of condensed matter physics, is the study of rigid matter, or solids, through methods such as quantum mechanics, crystallography, electromagnetism and metallurgy.
