FIG. 2.

Measured and calculated thermal conductivity as a function of temperature for three QDSs. Note the good agreement between the experimental and simulation results over a wide temperature range.

Image of FIG. 3.
FIG. 3.

Calculated normalized thermal conductivity as a function of the hopping parameter at (solid curve), (dashed curve), (dashed-dotted curve) and (dotted curve with small solid squares) for the dot size (circled) and polycrystalline size (circled). For comparison, experimental data obtained for three QDSs is also shown (large solid symbols).
