    Abstract

    Two-phonon absorption spectrum was measured for wurtzite GaN and was compared with two-phonon density of states of zinc-blende GaN obtained by lattice-dynamical calculations with an adiabatic bond-charge model. All structures in the spectrum were well explained by phonon structures of zinc-blende GaN. As a method to analyze two-phonon absorption spectra of wurtzite materials, proposed was the utilization of phonon dispersion curves of corresponding zinc-blende modifications, and the method was found to be useful.
