The evolution of the optical phonons in layered semiconductor alloys SnSe (1– x ) S x is studied as a function of the composition by using polarized Raman spectroscopy with six different excitation wavelengths (784.8, 632.8, 532, 514.5, 488, and 441.6 nm). The polarization dependences of the phonon...
