Lattice Thermal Conductivity by using Awads Model
Faten Kassid Hachim
Abstract: The lattice thermal conductivity of Mg2Ge has been analyzed on the basis of the Awad's model in the temperature range (4-800)K, In the analysis the phonon scattering from boundary, point defects, four and three-phonon (normal and umklapp) processes has been considered. Good agreement with the experimental results has been obtained. The study broached whipped to the contributions of the transverse and longitudinal phonons in the total lattice thermal conductivity.
Keywords: thermal conductivity, phonons, Mg2Ge
