The phonon transport in Lennard-Jones silicon wire with contacts is investigated using non-equilibrium Green’s function. With the size decreasing, the significant reduction in the number of phonon modes leads to a smaller thermal conductance density. The dopant (Ge) atoms are used to substitute the...
