A high conduction band degeneracy (Nv=6) leads to an extraordinary figure of merit (zT) in n-type Mg3Sb2 thermoelectrics, while the p-type ones show a much inferior zT due to its lower Nv of only 1 due to the large energy offset (ΔE~0.4 eV) between the two valence bands. As the derivatives of Mg3Sb2, ternary AB2C2 (A=Eu, Yb, Ca, Sr, Ba; B=Mg, Zn, Cd; C=Sb, Bi) Zintls show a similar valence band structure
