Abstract
  • A Monte Carlo model is here considered to account for phonon heat transfer in 1D nanostructures (nanowires and nanorods) based on the Boltzmann equation, Bose-Einstein statistics and Debye parameters. We focus attention on metal oxide nanostructures obtained in our NLSX lab via CVD experiments and demonstrate by the simulations that the heat conductivity is expected to be size-depending upon the dimension of the transverse size of these nanomaterials. The model is tested for silicon to compare with previous literature and, therafter, applied to zinc oxide 1D nanostructures, which were reported in previous experimental work [1]. The role of boundary scattering is discussed. Thermal conductivity ?T is found out to be lower by a factor 2-3, with respect to the bulk ZnO, depending on transverse size of the 1D nanopillar.
