Large Anomalous Nernst Effect in Disordered CoPt Thin Films for Planar Thermoelectric Sensing

Advanced Electronic Materials, EarlyView.
Disordered CoPt thin films exhibit a large anomalous Nernst effect with strong dependence on Pt concentration. The transverse thermoelectric response reaches 3.22 µV K−1 near equiatomic composition and an ANE sensitivity of 0.3 µm A−1. The results reveal that composition‐controlled microstructure in sputtered CoPt alloys provides an effective route for

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 ...

Achieving Phonon‐Glass Electron‐Crystal Behavior in Fully Organic Flexible Thermoelectrics

Advanced Energy Materials, EarlyView.
Phonon‐glass Electron‐crystal (PGEC) behavior is demonstrated in fully organic composites consisting of conductive polymers (PEDOT:PSS) and soft polymeric fillers (PVA). The optimized PEDOT:PSS–PVA composite concurrently reveals delocalized transport and thermal conductivity close to its theoretical minimum, yielding a superior thermoelectric figure of

Theory of magnon-driven spin Seebeck effect

, 2010
The spin Seebeck effect is a spin-motive force generated by a temperature gradient in a ferromagnet that can be detected via normal metal contacts through the inverse spin Hall effect [K. Uchida et al., Nature (London) 455, 778 (2008)].

Synergistic Bi–Te Antisite Defects and Crystalline‐Amorphous Hybrid Structure Enable Record‐High Thermoelectric Performance in Flexible Bi2Te2.7Se0.3 Films

Advanced Energy Materials, EarlyView.
Flexible n‐type Bi2Te3 thin films require improved room‐temperature figure of merit (ZT) and mechanical stability. We show that synergistic Bi–Te antisite tuning and crystalline–amorphous hybridization optimizes carrier concentration, mobility, and phonon scattering.
