Interfacial Reconstruction Enables Enhanced Thermoelectric Performance in Bismuth Telluride-Based Alloys. [PDF]

Adv Sci (Weinh)
Bismuth telluride‐based alloys are benchmark thermoelectric materials for near‐room‐temperature applications. Here, SnSe‐induced interfacial reconstruction simultaneously optimizes carrier and phonon transport in Bi0.4Sb1.6Te3, achieving a peak ZT of ∼1.38 at 363 K and a device efficiency of ∼6.47%, providing an effective strategy for high‐performance ...

Evidence for Itinerant Ferromagnetic Flat Bands Producing Large Transverse Responses

Advanced Materials, EarlyView.
Itinerant ferromagnetic flat bands are demonstrated in GdCo5 with a high Curie temperature of 940K, a stacked honeycomb–kagome lattice, through angle‐resolved photoemission spectroscopy and magneto‐thermoelectric measurements. These topological flat bands generate large Berry curvaturte, producing gigantic anomalous Nernst effect with record‐high ...

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.
