Özet:

 

We report the results of a theoretical study on phonon dispersion curves   (PDCs) along the three principal symmetry directions, Debye temperature   variation, combined density of states (CDS) curves, two-phonon Raman/IR   peaks, and anharmonic elastic properties (third order elastic constants and   their pressure derivatives) of ZnTe. This new van der Waals three-body force   rigid shell model (VTRSM) incorporates the effect of van der Waals   interactions and three-body interactions into the rigid shell model of zinc   blende structure, where the short range interactions are operative up to the   second neighbors. Our results are in good agreement with the available   measured data for zinc telluride. It is concluded that this VTRSM will be   equally applicable to study the above properties of other zinc blende   structure solids.
