Notes:
Preliminary results for the phonon dispersion curves of hexagonal 4H-SiC fromexperimental inelastic neutron (INS) and X-ray scattering (IXS) are reported and contrasted withthose of cubic 3C-SiC and silicon. The experimental frequencies and scattering intensities are inexcellent agreement with those from first-principles calculations using density-functional methods.The relative merits of the two experimental techniques and aspects of the density functionalperturbation theory and the so-called frozen phonon method for the determination of the basicphonon properties are briefly outlined
