Raman Scattering of InAs 1-x-y Sb x P y Quaternary Alloys

The Raman scattering of InAs 1- x - y Sb x P 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...

Description
Summary:The Raman scattering of InAs 1- x - y Sb x P 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 x P y quaternary alloys exhibit a three-mode behavior.
