摘要
We present results of first- and second-order Raman-scattering experiments on hexagonal and cubic InN covering the acoustic and optical phonon and overtone region. Using a modified valence-force model, we calculated the phonon dispersion curves and the density of states in both InN modifications. The observed Raman shifts agree well the calculated Gamma-point frequencies and the corresponding overtone density of states. A tentative assignment to particular phonon branches is given.
