ZrCoBi based half Heuslers with high thermoelectric conversion efficiency
Abstract
A ZrCoBi-based p-type half-Heusler material can have a formula: ZrCoBi$$_{1-x-y}$$Sn$$_{x}$$Sb$$_{y}$$, 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: ZrCo$$_{1-x}$$Ni$$_{x}$$Bi$$_{1-y}$$Sb$$_{y}$$, 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.
