PHONON PROPERTIES OF SILICON NANOLAYERS Phonon properties of silicon nanolayers were studied using Born-von Karman lattice dynamics theory and Boltzmann transport equation with relaxation time approximation. It was shown that spatial confinement of phonons strongly influences the phonon energy spectrum as well as thermal conductivity. The influence of temperature and quality of external boundaries on thermal properties of silicon nanolayers was revealed. Keywords: silicon nanolayers, phonons, thermal conductivity.
