completely understood. The behaviour of the conductance is examined as kinks of varying angular intensity are included into nanowires. The effects on thermal transport are evaluated through molecular dynamics simulations, phononMonteCarlo simulations and classical solutions of the Fourier equation. A
phonon reflection specularity on the heat flux is also examined. It is found that, in general, the flow of heat through systems simulated through phononMonteCarlo methods is concentrated into a channel smaller than the wire dimensions, while this is not the case in the classical solutions of the
Fourier model.
