Abstract Scope |
The potential widespread adoption of thermoelectric (TE) technology in energy harvesting applications hinges upon the high-performance, reliable, and cost-effective module development. Half-Heusler (hH) alloys show great promise, especially for efficient and reliable thermal to electrical energy conversion at medium to high temperatures, due to their tunable and favorable electronic structures, diverse routes to manipulate phonon transport, thermal stability, and robust mechanical properties. The remarkable progress observed in the performance of hH materials in the past decade has elevated expectations and opportunities to realize these materials in real-world applications. This talk will summarize the most promising strategies developed in the past and provide perspectives for the future development of hH TE materials and devices by linking materials properties, interface engineering and device design and performance to accelerate the development of hH-based TE applications. Similar strategies could be applied to other promising TE materials, achieving high-performance materials and module development. |
