The calculation of thermal properties of low dimensional silicon nanostructures and phononic crystals is of interest for applications such as thermoelectric-based energy harvesting. Calculation can be done using a variety of methods, but often of interest are computer based molecular dynamics simulations. In this poster, results from Reverse Non-Equilibrium Molecular Dynamics (RNEMD) simulations of silicon nanowires and a silicon phononic crystal are presented. The thermal conductance of wires with varying lengths and radii are shown, and compared to the thermal conductance of the proposed phononic crystal. These results will lead into further investigations into methodological questions involving RNEMD, and how the temperature dependence of the thermal conductivity can affect the results of RNEMD simulations.
