Abstract
Lattice dynamics calculations have been performed for crystalline SiO2, using the two-body potential model developed by Tsuneyuki et al. [Phys. Rev. Lett. 61, 869 (1988)]. The computed phonon frequencies agree reasonably well with experiment. Minor deficiencies suggest that the Si–O force constant obtained from the model is too weak.Keywords
