Charge Transport and Carrier Polarity Tuning by Electrolyte Gating in Nickel Benzenehexathiol Coordination Nanosheets

Advanced Materials, EarlyView.
This work reveals that charge transport in nickel benzenehexathiol coordination nanosheets is governed by variable‐range hopping reflecting structural disorder. Electrolyte gating induces a switch in dominant carrier polarity from p‐type to n‐type and leads to an improvement in thermoelectric performance.

All‐Heat Control of Magnetization Dynamics on Van der Waals Magnets

Advanced Materials, EarlyView.
Heat dissipation in nanomagnetic devices mediated by femtosecond laser excitation constitutes one of the pressing challenges toward energy‐efficient information communication technologies. Here it is shown that heat and magnetization play together to determine the ultrafast spin dynamics of van der Waals magnets across any substrates and magnet ...

Toward Stable, High‐Energy, Partially Disordered Mn‐Rich Spinel Cathodes by Revealing and Mitigating Surface Degradation

Advanced Materials, EarlyView.
Mechano‐activated partially disordered spinel LiMn2O4 is demonstrated with high Mn utilization and a specific energy over 800 Wh kg−1 at the cathode active material (CAM) level. Surface degradation, caused by the Jahn‐Teller effect in baseline commercial carbonate electrolyte (Gen 2), intensifies Mn2+ dissolution and crosstalk at high potentials ...

Mitigating Mobile‐Ion‐Induced Instabilities and Performance Losses in 2D Passivated Perovskite Solar Cells

Advanced Materials, EarlyView.
This study addresses the challenges of mobile‐ion‐induced instability in perovskite solar cells. Introducing bilayer passivation with ammonium salts (EDAI₂/PEAI and ABS/PEAI) significantly reduces ion density and improves device stability. The approach mitigates the detrimental effects of PEAI‐induced ionic losses, enhancing both performance and ...
