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.

Theoretical search for half-Heusler topological insulators [PDF]

Physical Review B, 2015
We have performed ab-initio band structure calculations on more than two thousand half-Heusler compounds in order to search for new candidates for topological insulators. Herein, LiAuS and NaAuS are found to be the strongest topological insulators with the bulk band gap of 0.20 and 0.19 eV, respectively, different from the zero band gap feature ...

Finding unprecedentedly low-thermal-conductivity half-Heusler semiconductors via high-throughput materials modeling

, 2014
The lattice thermal conductivity ({\kappa}{\omega}) is a key property for many potential applications of compounds. Discovery of materials with very low or high {\kappa}{\omega} remains an experimental challenge due to high costs and time-consuming ...

Thermoelectric Property Mapping for High‐Performance Integrated MgAgSb‐MgCuSb System

Advanced Science, Volume 13, Issue 17, 23 March 2026.
From the property mapping of the MgAgSb–MgCuSb system, both thermoelectric materials and corresponding interface materials are optimized: Ag‐rich compositions provide higher PF and zT, whereas Cu‐rich side yields superior transport properties and low contact resistance.

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.
