Raman study of the crystalline structure and resonant scattering behavior in (AlxGa1−x)0.5In0.5P alloys is presented. The first-order longitudinal-optical phonon line shape shows asymmetric broadening which is explained by the spatial correlation model. The correlation length in this model is related to the size of domains due to the generation of the ordered structure. In resonant Raman scattering in (AlxGa1−x)0.5In0.5P alloys, we observe drastic enhancement of the Raman intensities. It is called scattered photon resonance, and the peaks are around the energy of interband transition related to the E0/E0+Δ0 at the Γ point.
