Image of FIG. 1.
FIG. 1.

Scheme of two coupled acoustic nanocavities jointed with two nanowires. Two identical cavities, i.e., cavity 1 and cavity 2, are coupled through a bridge with length and width .

Image of FIG. 2.
FIG. 2.

Total transmission coefficient vs reduced frequency for different lengths of the bridge between two nanocavities. The horizontal axis is scaled by the spacing between mode cutoff frequencies . Here, . These curves have been evenly spaced vertically for clarity. The dashed lines are guides to the eye. C1 and C2 denote cavity 1 and cavity 2, respectively. Hereafter, we always choose and . The insets show the calculated structures with different materials in which filled areas denote AlAs; others are made of GaAs.

FIG. 3.

Transmission coefficient of the zeroth mode vs the bridge length and the incident phonon frequency . (a)–(d) correspond to the structures in Fig. 2(a)–2(d), respectively. Others are the same as those in Fig. 2.

FIG. 4.

Total transmission coefficient as a function of the reduced frequency for different bridge length : (a) and (b) . The dotted, dashed, dash-dotted, and solid curves correspond to cases (a)–(d), respectively. Here, materials M1 and M2 are AlAs and GaAs, respectively. Others are the same as those in Fig. 2.

Image of FIG. 5.
FIG. 5.

Thermal conductance divided by temperature, , as a function of reduced temperature for different material properties. [(a)–(a1)] Materials M1 and M2 are GaAs and AlAs, respectively. [(b)–(b1)] Materials M1 and M2 correspond to AlAs and GaAs, respectively. The solid, dash-dotted, dotted, and dashed curves correspond to cases (a)–(d), respectively. (a) and (b) are for the total thermal conductance, and (a0) and (b0) and (a1) and (b1) are for the thermal conductances of zeroth and first modes, respectively. Here, and . Others are the same as those in Fig. 2.
