Abstract

In frame of De Launay model we calculated phonon dispersion of graphene in ГM direction using radial and tangential force constants for first four neighbor atoms. Calculated phonon dispersion is in satisfactory agreement with experimental phonon spectra of graphite. In long wave approximation we estimated elastic modulus of graphene in comparison with experimental results for graphite and carbon nanotube.
