Abstract

The lattice dynamical calculations are performed on some type-I and type-II alloys by using the third-neighbor Clark-Gazis-Wallis (CGW) model. The theory is used to compute the phonon dispersion curves, the frequency spectra and the lattice specific heat of the studied alloys. The obtained results are in good agreement with the experimental findings, and better than those obtained using other models.
