## Description

- description: BaZrO3 and KTaO3 are two rare examples of perovskite oxides that retain
    the ideal cubic structure down to the lowest temperature. In this paper, we report
    thermal conductivity (κ) between 300 and 773 K on single crystals of these compounds.
    For BaZrO3, the κ of 7.5 Wm−1K−1 at 300 K is ∼40% larger than the previously reported
    polycrystalline values. For KTaO3, our value of 13.1 Wm−1K−1 at 300 K clarifies
    the sources of error in some of the previously reported data. These results underscore
    the importance of high-quality experimental data in benchmarking the accuracy
    of advanced first-principles κ calculations.
