The lattice-dynamic properties of GaP/sub 1/..sqrt../sub x/Sb/sub x/ have been investigated for the first time by using Raman scattering measurements. This alloy, which has a large miscibility gap, has been grown by organometallic vapor phase epitaxy. The first-order Raman spectra for the ternary samples show two mode behavior over the whole composition range. The composition dependence of the intensity and energy shift of each mode is reported. The broadening and asymmetry of the GaP longitudinal-optical modes are analyzed in terms of alloy disorder effects
