Boron nitrideSpectroscopySimulationUsing the spectral moments method, the calculations of the Raman spectra of single-walled boron nitride nanotubes (SW-BNNTs) were performed in the framework of the force constants model. Spectra were computed for chiral and achiral nanotubes for different diameters and...

摘要: Raman spectra of single-walled boron nitride (SW-BN) nanotubes (NTs) are calculated by the ab-initio Hartree–Fock (RHF) methods. Calibration procedure is proposed to fit calculated spectra to experimental frequency is shown to be peculiar to armchair (n,n) SW-BN-NT.关键词:...
We present Raman spectra of cubic boron nitride (cBN) to 40 GPa and up to 2300 K that show a continuous pressure and temperature shift of the frequency of the transverse optical mode. We have also obtained high-pressure Raman spectra from a new noble metal nitride, which we synthesized at...

Pure water was loaded into the chamber of the HDAC together with a single crystal of quartz and cubic boron nitride. The experimental pressure was estimated according to the Raman shift of the 464 cm-1 peak of quartz. The sample was heated by two small furnaces made of NiFe alloy wires ...
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),...
