%X By using the scattering-matrix method and the scalar model of elasticity, we investigate the effect of controllable defects on low temperature thermal conductance in a nanowire with a quantum box geometry. It is found that the thermal conductance can be controlled by adjusting the parameters of the defects. The size and the position of the defect can induce the variation in thermal conductance. It is also found that the behavior of the thermal conductance versus temperature is different for different types of defects.
