Abstract :
We present phonon measurements carried out on NbSi/sub 2/, TaSi/sub 2/ and VSi/sub 2/, using neutron inelastic scattering and Raman spectroscopy in comparison with phonon properties previously investigated by other techniques: the Debye temperature values obtained from low temperature specific heat and resistivity measurements and the phonon spectra issued from point-contact spectroscopy.
