FIG. 1.

Through-thickness lattice thermal conductivity of single-period (circles), alternating-period (up triangles), and multiple-period (squares) NDSLs plotted as a function of (a) mole fraction of PbSe; (b) superlattice period ; (c) growth temperature ; and (d) growth rate . Solid symbols are for -doped samples and open symbols are for -doped samples. Data points with error bars are from this study; data points without error bars are drawn from the literature. If not otherwise specified, , , , and . In part (a), ; and the in-plane of superlattices (diamonds) (Ref. 12) and cross-plane of a superlattice (down triangle) (Ref. 13) are included for comparison. The dashed and solid lines in (a) are the measured (Ref. 4) and calculated [using from Eq. (1)] of bulk alloys, respectively. The dashed lines in (b), (c), and (d) are of an MBE-grown thin film and are included as a baseline for comparisons.

FIG. 2.

Through thickness lattice thermal conductivity of -doped NDSLs (open circles), compared to of bulk alloys from Ref. 17 (left triangles) and Ref. 18 (right triangles). The superlattice periods are . The dashed line is of an MBE-grown thin film and is included as a baseline for comparisons. The solid line is the lattice thermal conductivity of the alloys calculated using the Debye-Callaway model, using from Eq. (1).

Compilation of the lattice thermal conductivity of NDSLs (open up triangles) and NDSLs (open circles) measured in this work with comparison to superlattices (diamonds, Ref. 12) and superlattices (down triangle, Ref. 13); bulk (solid up triangles, Ref. 4), (solid circles, Refs. 17 and 22), (left triangles, Refs. 17 and 23) and (squares, Ref. 17) alloys. is the impurity scattering cross section discussed in text, see Eq. (1). The solid line is the calculations of the Debye–Callaway model for a hypothetical PbTe solid with the corresponding impurity scattering cross section .
