Raman spectra of TiN/AlN superlattices

RETRACTED: Characterization and mechanistic analysis of the visible light response of cerium and nitrogen co-doped TiO2 nano-photocatalyst synthesized using a one-step technique

“…They can be ascribed to the specific Raman modes of anatase titanium dioxide [33][34][35]. Furthermore, it was demonstrated that bands at 515 cm −1 corresponding to the A 1g mode are the Ti-O stretching type vibration, bands at 395 cm −1 corresponding to the B 1g mode are the Ti-O stretching type vibration, and the bands at 635 cm −1 corresponding to the E g mode are the O-Ti-O bending type vibration [34,35]. From Fig.…”

Comparative Study of Dendrimer‐Templated Nitrogen‐Platinum Co–Doped TiO2 for the Photocatalytic Degradation of Azo Dyes in Contaminated Water

“…These modes were assigned to anatase crystalline structure. However, the N, Pt TiO 2 PAMAM G1 showed more intense Raman peak intensity for all bands of TiO 2 in comparison with PAMAM G0 and HPEI templated N, Pt TiO 2 nanomaterials . This Raman peak intensity increase suggests an enhanced crystallinity .…”

“…However, the N, Pt TiO 2 PAMAM G1 showed more intense Raman peak intensity for all bands of TiO 2 in comparison with PAMAM G0 and HPEI templated N, Pt TiO 2 nanomaterials. [34,35] This Raman peak intensity increase suggests an enhanced crystallinity. [36] There may possibly be a slight variation in the Raman vibrational modes, because of the fractional substitution of O by N, which is too insignificant to be observed.…”

Effect of carbon doping on microstructure, electronic and magnetic properties of Cr:AlN films

“…Chen et al have demonstrated that a tensile stress would induce Raman spectra blue-shifted for c-axis texture films [23]. Bernard et al have showed that N vacancy is another factor for increase of Raman shift [25]. In Table 1, peaks A and B in Fig.…”

“…This further demonstrated that the Cr atoms located in the AlN crystal lattice. Additionally, the stress and deficiency of N or Cr could move the Raman shifts [23][24][25]. Chen et al have demonstrated that a tensile stress would induce Raman spectra blue-shifted for c-axis texture films [23].…”
