Figure 6. (A) Temperature-dependent total thermal conductivities κtotal(T); (B) temperature-dependent Lorenz numbers L(T); (C) temperature-dependent lattice and bipolar thermal conductivities κL + κb(T) of the hot-pressed BST+HEAx (x = 0, 0.1, 0.5, and 1.0 vol%) samples for Pa- and Pe-directions; (D) room-temperature lattice thermal conductivities κL as a function of the HEA concentrations. HEA: High entropy alloy; BST: Bi0.4Sb1.6Te3.
