Role of samarium atoms in the formation of the structure of As-Se-S chalcogenide vitreous semiconductors

The Raman spectra of films of samarium-doped As-Se-S three-component chalcogenide vitreous semiconductors are studied. It is shown that the spectra are constituted by four bands in the frequency ranges 10–100, 195–290, 290–404, and 420–507 cm −1 , which strongly vary with doping. The structural unit...
