This work reports the thermal conductivity of RbV3Sb5 and CsV3Sb5 withthree-dimensional charge density wave phase transitions from 80 K to 400 Kmeasured by pump-probe thermoreflectance techniques. The in-plane (basal plane)thermal conductivities are found moderate, i.e., 12 W/mK of RbV3Sb5 and 8.8W/mK of CsV3Sb5 at 300 K. Low cross-plane (stacking direction) thermalconductivities are observed, with 0.72 W/mK of RbV3Sb5 and 0.49 W/mK of CsV3Sb5at 300 K. A unique glass-like temperature dependence in the cross-plane thermalconductivity is observed, which decreases monotonically even lower than theCahill-Pohl limit as the temperature decreases below the phase transition pointTCDW. This temperature dependence is found to obey the hopping transportpicture. In addition, a peak in cross-plane thermal conductivity is observed atTCDW as a fingerprint of the modulated structural distortion along the stackingdirection.
