The effect of surface bond reconstruction of thermal contact surfaces on phonon transport in atomic wire.

The effect of surface bond reconstruction (SBR) of Si contact surfaces on phonon transport in Si atomic wire is investigated. Green’s function method is applied to calculate the thermal conductance and local heat currents. Results show that the phonon transport in atomic wires is enhanced significantly by SBR at the thermal contact surface. A blue shift for phonon transmission function is induced by the SBR.
