چکیده انگلیسی
Neutron diffraction study is a useful tool for the direct observation of structural changes in amorphous and liquid materials. Chalcogenide composites in liquid and glassy forms are important materials for technological applications in Optics and Electronics. Study of collective excitations in such materials is very useful in providing insights into their structural aspects. In this study phonon dispersion calculations on Te-I liquid systems at different temperatures are reported and discussed. The theory of liquids as developed by Hubbard and Beeby and the self consistent method of Takeno and Goda are applied to analyze the phonon dispersion of TeI system. From the frequency spectrum the velocity of sound and hence various thermo-elastic properties of Te-I liquid systems at different temperatures are determined.
