Thermal conductivity of SrTiO3 and KTaO3 measured by time-domain thermoreflectance in a diamond anvil cell. We measured 4 SrTiO3 samples and 3 KTaO3 samples. We also measured the longitudinal speed of sound along [100] direction of these two materials by stimulated Brillouin scattering.

Steps to reproduce
Use the bidirectional heat diffusion model to analyze the TDTR data. For the Brillouin scattering data, you can use FFT to extract the frequency then calculate the sound velocity.
