Phonon Properties

Simple lattice dynamical models have been fitted to the experimental phonon dispersion curves of niobium, molybdenum, and their alloys. The 'best-fit' parameters are used to compute the phonon distribution functions, g(v), and several properties which depend on these functions.

Phonon Properties

We have reported the phonon properties of AmS by using breathing shell models (BSM) which includes breathing motion of electrons of the Am atoms due to f-d hybridization. The phonon dispersion curves, density of states and specific heat calculated from present model. The calculated phonon dispersion curves of AmS are presented follow the same trend as observed in uranium sulphide. We have discussed the significance of this approach in predicting the phonon dispersion curves of this compound and examine the role of electron-phonon interaction.
