Dependence on volume of the phonon frequencies and the ir effective charges of several III-V semiconductors

Abstract
The mode Grüneisen parameters of the LO and TO Raman phonons of AlN, BN, and BP, and the dependence of eT* on lattice constant have been measured by Raman scattering in a diamond anvil cell. The results for eT* are interpreted by means of pseudopotential calculations of eT* versus lattice constant.
