Description

Nanostructed materials make it possible to tailor the vibrational properties of a system for specific uses like thermoelectric applications or phononic waveguides. In this work, the vibrational properties of two-dimensional silicon nanostructures are studied. The nanostructures are build from arrays of nanowires that are arranged in such a manner that they form a periodic lattice. The method of molecular-dynamics simulations is used to calculate the vibrational properties. Results will be shown for the vibrational density of states as well as dispersion relations at long wavelength.
