The Raman scattering of InAs_<1-x-y>Sb_xP_y quaternary alloys grown on (100) InAs substrates by liquid-phase epitaxy is studied in this work. The peaks at 182,216,234 and 312 cm^<-1> in the Raman spectra are assigned as the InSb LO, InAs TO, InAs 1LO and InP LO modes, respectively. The mode of 476 cm^<-1> is assigned as the second-order Raman mode, InAs 2LO Raman mode. Also, both the 228- and 303-cm^<-1> lines are attributed to the disorder-activated optical phonons. In addition, the Raman scattering spectra in InAs_<1-x-y>Sb_xP_y quaternary alloys exhibit a three-mode behavior.
