Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

Advanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

Critical Role of Polymer Gate Dielectrics on the Charge Carrier Transport in Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
Charge transport in 2D tin perovskite FETs is shown to be governed by dielectric interface behavior. Polar polymer dielectrics induce dipolar disorder that localizes carriers, whereas nonpolar polymers suppress trapping and enable superior charge transport, ensuring stable and reliable transistor operation. ABSTRACT Understanding the role of interfaces

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

Advanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...
