Dec 13, 2019 · In this work, the spectral analyses of the unique Raman signals of Sn oxide SNCs are complemented by theoretical structural and vibrational analyses to clarify the origin of the Raman characteristics of SNCs.

Mar 1, 2021 · Sn 1−x Fe x O 2 (x = 0.00, 0.1, 0.12, 0.16 and 0.18) nanoparticles have been synthesized by ball milling. Analyses of the Raman spectra exhibit a strong correlation between the internal structure of the nanoparticles and their electrical and magnetic properties.

Nov 14, 2024 · Raman spectra of both SN polymorphs were recorded from NBSC shapes produced by forming green bodies from silicon and SiC grains and firing these shapes in an N 2 atmosphere to 1723 K. A heating rate of 7 K/min was used (Forschungsgemeinschaft Feuerfest e.V., Höhr-Grenzhausen, Germany).

Mar 22, 2023 · The Raman characterization of the Sn-mixed Ga 2 O 3 polycrystalline compounds (0.00 ≤ x ≤ 0.30), which were produced by the high-temperature solid-state synthesis method, indicated that the Sn-induced changes in the chemical …

Jul 5, 2018 · We investigated interlayer phonon modes of mechanically exfoliated few-layer 2H-SnS 2 samples by using room temperature low-frequency micro-Raman spectroscopy. Raman measurements were performed...

Sep 15, 2000 · Raman scattering spectra of polycrystalline and all with the type-I clathrate crystal structure, were studied at room temperature and 10 K. Several of the Raman-active vibrational modes in these compounds have been identified.

May 12, 2011 · In the present work, we report the synthesis of SnS nanoparticles by wet chemical method and characterization done using AFM, TEM for size and morphology and XRD for phase identification, followed by detailed optical absorption, photoluminescence and Raman spectroscopic studies addressing the direct and indirect band gap transitions and all the ...

Submillimeter-sized single crystals of SnO exhibiting well-defined symmetric shapes of four-armed star and square plate were successfully synthesized through a mild surfactant-free hydrothermal...

Nov 15, 1997 · The frequencies, widths, and shapes of the one-phonon Raman spectra of isotopically enriched and highly isotopically disordered α-Sn samples have been measured. The isotopically enriched samples show a frequency inversely proportional to the square root of the mass, in agreement with the harmonic approximation, and a linewidth inversely ...

Oct 17, 2017 · In this work, we have successfully synthesized SnS flakes with different thicknesses and systematically investigated their polarization-dependent Raman properties. It is found that the different Raman mode of SnS shows distinctly anisotropic thickness dependence. For B 3g mode, the polar plot of Raman intensities is insensitive to the flake ...
