Abstract
To study the lattice dymamics of GaP-InP having Zinc-blende structure in a new non-central rigid ion model (NC-RIM) which in corporates three types of interactions (i) Non-coulombic forces (ii) Coulombic forces (iii) Bond bending forces has been used developed. The model involves seven model parameters; we used six critical point phonon frequencies, two elastic constants. The applications of the present model (NC-RIM) have been made to calculate the phonon dispersion relations, Debye characteristic temperature and specific heat of GaP-InP. The comparision of theoretical results with the available experimental data has been made along the three sysmmetry direction [100], [110] and [111]. A reasonably good agreement observed between theory and experiments.
