Carbon nitrideRaman spectroscopyStructureA general model is presented for the interpretation of the Raman spectra of amorphous carbon nitrides measured at any excitation energy. The Raman spectra can be explained in terms of an amorphous carbon based model, without need of extra peaks due to CN, ...

Their Raman spectra are discrepant in position, width, and intensity of Raman peaks. Here, we take hexagonal boron nitride (hBN, insulator), Bi2Se3 (topological insulators), hexagonal MoS2 (2H-MoS2, in-plane isotropic semiconductors), black phphosphorus (BP, in-plane anisotropic semiconductors),...

The Raman spectra of the molybdenum hexacarbonyl completely vanish at 23.3GPa, signifying novel pressure induced decomposition. The decomposed Raman spectrum recovered at ambient conditions has the characteristic features of a highly dense polymer with δ(OCO) units possibly attached to metal centers, C...

With a spatial correlation model, a simple method was established to evaluate the crystallinity and stress of cubic boron nitride (cBN) films from the variation of linewidth and peak shift of Raman spectra. An increase of crystallinity and a decrease of stress of the cBN films with growth time...
In this work, we propose a new procedure to calculate Raman spectra of polar, fine-grained materials from first principles, which allows to reproduce with unprecedented accuracy their asymme- trical and broad spectral shape, thereby enabling precise phonon mode assignment also in these materials. ...
Spectra have not been scaled; data are offset vertically for clarity. The spectral region dominated by the first-order Raman peak of the silicon substrate around 520 cm−1 has been omitted. The spectral feature at ~300 cm−1 is a second- order Raman peak of silicon56. interaction ...
