Résumé:
Indium nitride under high pressure (up to 50 GPa) was analyzed by means of Raman spectroscopy. The wurtzite to rocksalt phase transition was evidenced at the pressure of 13.5 +/- 0.5 GPa and the pressure dependence of vibration modes of both structures was investigated, leading to the determination of linear pressure coefficients and mode Gruneisen parameters. Influence of the pressure dependence of the energy gap on the spectra intensity is also discussed.
