All‐Scale Hierarchical Structure Contributing to Ultralow Thermal Conductivity of Zintl Phase CaAg(0.2)Zn(0.4)Sb
TiNiSi‐type Zintl phase CaAgSb can transform into LiGaGe‐type Zintl phase CaAg(x)Zn((1−) (x) ()/2)Sb when some of the Ag atoms are substituted by Zn atoms, leading to an ultralow thermal conductivity of ≈0.4 W m(−1) K(−1) in the whole measured temperature range of CaAg(0.2)Zn(0.4)Sb. The microstruct...
