Phonon spectra of carbon nanotubes
Khokhryakov N. V. , Savinskii S. S. , Molina J. M.
The results of a numerical calculation of the vibrational spectra of graphite nanotubes of optimized structures are presented. This is the first time that the deformation of the wave functions of valence electrons is explicitly taken into account, on the basis of a parametric tight-binding model, in calculating the stiffness matrix of a nanotube. The results agree with the experimental data obtained by the Raman spectroscopy method. © 1995 American Institute of Physics.
