  • High-efficiency two-phase heusler thermoelectric materials
    Patent number: 11302855
    Abstract: A thermoelectric material may be composed of an isostructural pair of Heusler compounds, either a pair of full Heusler (FH) X2YZ compounds or a pair of half Heusler (HH) XYZ compounds. In the FH pair, a first compound of the pair may the formula (X1)2Y1Z1, wherein X1 is selected from Fe and Co; Y1 is selected from Ti, V, Nb, Hf, and Ta; and Z1 is selected from Al, Ga, Si, and Sn and a second compound of the pair has the formula (X2)2Y2Z2, wherein X2 is selected from Mn, Fe, Co, Ru, and Rh; Y2 is selected from Ti, V, Mn, Zr, Nb, Hf, and Ta; and Z2 is selected from Be, Al, Ga, Si, Ge and Sn. The first and second compounds of the pair may share two elements in common and have third elements which are different and are either isovalent or have a valency which differs by ±1.
