Strain-tunable triple point Fermions in diamagnetic rare-earth half-Heusler alloys [PDF]

Scientific Reports, 2021
Topologically non-trivial electronic structure is a feature of many rare-earth half-Heusler alloys, which host atoms with high spin-orbit coupling bringing in the non-triviality.

Half-Heusler alloys as emerging high power density thermoelectric cooling materials. [PDF]

Nat Commun, 2023
AbstractTo achieve optimal thermoelectric performance, it is crucial to manipulate the scattering processes within materials to decouple the transport of phonons and electrons. In half-Heusler (hH) compounds, selective defect reduction can significantly improve performance due to the weak electron-acoustic phonon interaction.
