(color online) Electronic thermal conductivity κ _e (W⋅m⁻¹⋅K⁻¹) map of PbS_xTe_{1 − x} with (a) x = 0.25, (b) x = 0.5, and (c) x = 0.75 as a function of carrier concentration and temperature, respectively. The negative scale of x axis stands for the n-type, while the positive scale represents the p-type.
