“…In a-Si:H, the SiH 3 radicals causes a degenerate deformation and symmetric deformation modes at 907 cm -1 and 862 cm -1 respectively. The absence of these modes in a-Si,S:H alloys' spectra suggests negligible SiH 3 bonding in these alloys [19].…”

“…This difference in electronegativity is responsible for the shift in the phonon vibrational mode peak to higher wave numbers. Bonding of sulphur atoms to the Si-matrix is also expected to activate the Si-TO-like mode in a-Si,S:H alloys [19]. However, since the electronegativity of S (4.1) is less than that of F or Cl, only a small shift of the phonon band is expected to occur, and the strength of the resulting i.r.…”
