Vibrational Properties of Single Wall Carbon Nanotubes inside Boron nitride Nanotubes using Raman spectroscopy

Polarized Raman spectra of single-walled carbon nanotube (SWCNT) inside single-walled boron nitride nanotube (SWBNNT) are calculated as a function of their diameter and chirality. The spectral moment's method was shown to be a powerful tool for determining vibrational spectra (infrared absorpti...

Summary:Polarized Raman spectra of single-walled carbon nanotube (SWCNT) inside single-walled boron nitride nanotube (SWBNNT) are calculated as a function of their diameter and chirality. The spectral moment's method was shown to be a powerful tool for determining vibrational spectra (infrared absorption, Raman scattering and inelastic neutron-scattering spectra) of harmonic systems. The calculations of vibrational properties of double-walled hybrid nanostructures SWCNT inside SWBNNT (SWCNT@SWBNNT) are performed in the framework of the force constants model, using the spectral moment's method (SMM). To describe the Van der Waals interactions between inner and outer tubes in hybrid systems, we used a Lennard-Jones potential. These predictions are useful to interpret the experimental data.
