Robustness of Half‐Metallicity and Spin‐Dependent Transport in Defective Co2HfSn and Co2ZrSn Heusler Alloys

Advanced Electronic Materials, EarlyView.
Point defects strongly influence the spin‐dependent electronic and transport properties of Co2HfSn and Co2ZrSn Heusler alloys. First‐principles calculations reveal that Co vacancies preserve half‐metallicity, while anti‐site and swap defects introduce minority‐spin states that reduce spin selectivity.

3D MXene Aerogel Frameworks With In Situ‐Grown BiFeO3 for Synergistically Enhanced Thermoelectric Performance

Advanced Electronic Materials, EarlyView.
A lightweight, 3D MXene aerogel framework integrated with bismuth ferrite was developed to efficiently harvest waste heat. By growing the oxide directly onto the porous aerogel, the composite achieves strong interfacial connections. This unique architecture simultaneously boosts electrical power generation and blocks heat flow, resulting in an ...

Rare‐Earth Yttrium Doping Advances High‐Performance AgSbTe2 Thermoelectrics

Advanced Energy Materials, EarlyView.
Y‐doped AgSbTe2 achieves band and microstructure co‐optimization, with coherent Y‐Ag2Te interfaces enhancing phonon scattering and reducing lattice thermal conductivity to 0.26 W m−1 K−1. Combined with valence‐band broadening and increased carrier concentration, this yields ZT ≈ 2 at 623 K, average ZT = 1.5, and 7.3 % conversion efficiency of a single ...
