Lattice thermal conductivity of SiC nanowires

We present non-equilibrium classical molecular dynamics simulations for the lattice thermal transport of SiC nanowires and bulk beta-SiC. The thermal conductivity of the nanowires is strongly reduced compared to the SiC bulk value. In our approach only the phonon contribution to the heat flow is considered, neglecting any electronic components. We investigate the dependence of the thermal conductivity on the wire cross section and consider the influence of different wire surfaces on the thermal transport.
