Abstract

In this work. linewidth variations versus compositions of the first-order longitudinal optic (LO) phonon modes in the mixed alloy system are studied. The asymmetry and broadening of the LO modes is explained using a “spatial correlation” model with a Gaussian correlation function. The system investigated here were In1-x-yGaxAlyAs quaternary alloys lattice-matched to InP(with x+y ≈47%). The quaternary alloy samples were grown as epilayers on (001) InP substrates by molecular beam epitaxy(MBE).
