Thermal transport properties of Bi1 − xPbxCuSeO. a Temperature-dependent lattice thermal conductivity κL. b Pb-content-dependent κL at 300, 473, 673, and 873 K. The solid lines in b were estimated by the Debye–Callaway model for 300 and 873 K. The error bars in a, b are both 20%, as the uncertainties of the total and electronic thermal conductivity are both estimated to be ~10%
