De Launay's angular force model for β-SiC

Abstract

Phonon dispersion relations of β-SiC along [100] and [111] directions have been calculated using de Launay's angular force model. The noteworthy features of the present approach are that the number of parameters used is comparatively smaller and Si-Si and C-C interactions are taken to be different. The agreement between the theoretical and experimental results is reasonably good. © 1973.
