Abstract

The effect of high pressure on the one- and two-phonon Raman spectra of ZnTe, ZnSe, and ZnS has been measured up to their metallic phase transitions, at 95, 137, and 150 kbar respectively. Zone boundary transverse acoustic phonons "soften" with pressure in each case. For ZnTe, ZnSe, ZnS, Si, and GaP a linear correlation is found between the mode Grüneisen parameters for TA(X) and the transition pressures.
