This work is focused on the compositional dependencies in the Raman spectra of amorphous Ge-As-Se and Ge-Sb-Te chalcogenides with the systematic increase of the Ge-content. Studied Ge-As-Se and Ge-Sb-Te chalcogenides are promising for applications in the photonics, optical, and electronic data storages. Gaussians used to fit the obtained Raman spectra were attributed to the vibrations of the structural...
