In this thesis we study the vibrational properties of different nanostructures
by using the continuum and the discrete models.
The continuum method is based on the elasticity theory while the discrete
method employs the molecular dynamics.
With the continuum method we obtain the dispersion curves and the
displacement patterns of the vibrational modes. We also calculate the radial
acoustic modes of cylinders, cylindrical shells, "core-shell" and composite
cylinders of general anisotropy.
We finally use the Surface Green Function Matching method to obtain
the acoustic waves dispersion curves in superlattices formed by anisotropic
hexagonal crystallographic materials.
With the discrete method, we develop a technique for the calculation of
the density of states and the Raman spectra from the data obtained by the
molecular dynamics approach.
