Researchers Reveal the Conduction Band Engineering of Half-Heusler Thermoeletrics with Orbital Chemistry

Caption

Fig. 1. There are two different conduction band minima (CBMs) arise at the X point (valley degeneracy NvX=3) in the Brillouin zone, one dominated by the d-orbital of X atoms (minimum at energy EX2, red sphere) and one dominated by the d-orbital of Y atoms (minimum at energy EX3, green sphere).
