Abstract: A ZrCoBi-based p-type half-Heusler material can have a formula: ZrCoBi1-x-ySnxSby, where x can vary between 0.01 and 0.25, and y can vary between 0 and 0.2. An average dimensionless figure-of-merit (ZT) for the material can be greater than or equal to about 0.80 as calculated by an integration method for temperatures between 300 and 973 K. A ZrCoBi-based n-type half-Heusler material can have a formula: ZrCo1-xNixBi1-ySby, where x can vary between 0.01 and 0.25, and y can vary between 0 and 0.3. The material has an average dimensionless figure-of-merit (ZT) is greater than or equal to about 0.65 as calculated by an integration method for temperatures between 300 and 973 K.
