Abstract Scope |
Half-Heusler (HH) materials have been extensively researched for their potential applications in the field of thermoelectric materials, as well as spintronics and magnetic applications. For the thermoelectric application, high thermal conductivity has been a constant challenge in the realm of HH-based thermoelectric materials. To tackle this problem, a relatively new concept, referred to as double half-Heusler (DHH) and Triple half-Heusler (THH) have been proposed as a strategy to decrease lattice thermal conductivity. In this talk, I intend to introduce strategy to design compositions of these DHH and THH to further extend this innovative idea to broader range of studies. The lattice thermal conductivity of DHH and THH (κL<6W/m K) are lower than half-Heusler standards (κL>15W/m K), which can result in improved thermoelectric performance. Additionally, the potential for p-n transitions, high entropy alloy-type compositions, and module fabrication, utilizing an unconventional valence balance strategy, will be discussed. |
