Fig. 6. (Color online) (a) Calculated power factors (PF) of some selected chalcogenide perovskites having a PF > 2 mW-m^–1K^–2. The prototype of each structure is also shown. (b) Side view and (c) top view of distorted perovskite structure of BaZrS₃. (d) Lattice thermal conductivity (LTC) of BaZrS₃ at different temperatures along the three different crystallographic axes. The inset, a magnified section of the LTC, shows the lack of anisotropic effect for κ_L of BaZrS₃. The vertical line in the inset is the LTC at 300 K (κ_L = 1.20 W/m^–1K^–1).
