摘要：

We have investigated the pressure dependence of the phonon dispersion of the transverse acoustic branches of GaSb by inelastic neutron scattering at 300 K. Frequency variations were measured along the [100], [110], and [111] directions up to 7 GPa, i.e. over the entire stability range of the zincblende structure. A strong softening is observed for zone boundary modes. These results are compared with published data on Ge up to 10 GPa as well as with first-principle calculations. We find generally good agreement between experiment and theory. The calculations reveal a strong pressure dependence of the Gruneisen parameters.
