Glass-like Cross-plane Thermal Conductivity of Kagome Metals RbV3Sb5 and CsV3Sb5
Abstract This work reports the thermal conductivity of RbV 3 Sb 5 and CsV 3 Sb 5 with three-dimensional charge density wave phase transitions from 80 K to 400 K measured by pump-probe thermoreflectance techniques. At room temperature, the in-plane (basal plane) thermal conductivities are found moderate, i.e., 12 W …
