Unraveling the Mg Loss Mechanism and Degradation Kinetics in Thermoelectric n‐Type Mg2Si‐Mg2Sn Solid Solutions

Advanced Functional Materials, Volume 36, Issue 25, 26 March 2026.
Mg‐based thermoelectrics are among the most promising candidates for power generation applications but their performance is compromised by Mg loss at device operation temperatures due to the higher chemical potential of Mg (μMg${\mu}_{\mathrm{Mg}}$) inside the material compared to the environment.

Enhancement of the Thermoelectricity in Half‐Heusler TaRuAs by Substitutional Doping

Annalen der Physik, Volume 538, Issue 3, March 2026.
The electronic structure and thermoelectric response of the half‐Heusler compound TaRuAs are studied based on density functional theory, deformation potential theory, and Boltzmann transport theory. The effects of doping are elucidated adopting both the rigid band approximation and supercells that explicitly include the dopant atoms.
