    • An upper bound is imposed by the observation that thermal conductivities in short-period superlattices tend to be lower than those in the corresponding random alloys [e.g., T. Borca Tasciuc et al., J. Appl. Phys. 92, 4994 (2002)].

    • On the other hand, the thermal resistivities reported for quantum cascade lasers would be inconsistent with any value that is significantly lower. Near ambient, alloy and superlattice thermal conductivities tend to be relatively independent of temperature. While a significant anisotropy between the thermal conductivities in the vertical and in-plane directions was observed for Si/Ge superlattices [B. Yang, W. L. Liu, J. L. Liu, K. L. Wang, and G. Chen, Appl. Phys. Lett. 81, 3588 (2002)],
