Siloxane Decorated Water‐Obstructing Guest for Efficient Air‐Processed OSCs

Advanced Science, EarlyView.
The Water‐obstructing Guest (WOG) strategy, employing a siloxane decorated polymer D18‐SiO as a capping layer, is proposed to minimize moisture penetration while preserving original morphology and suppresing trap density in high humidity condition. WOG‐based Organic solar cells, fabricated at 90% relative humidity (RH), achieved a power conversion ...

Subsurface Oxygen Vacancy Mediated Surface Reconstruction and Depolarization of Ferroelectric BaTiO3 (001) Surface

Advanced Science, EarlyView.
In‐situ atomic‐scale electron microscopy reveals that vacuum‐annealed ferroelectric BaTiO3 (001) surfaces exhibit BaO termination with periodic Ba deficiency and TiOx adunits. Planar oxygen vacancy accumulation in the subsurface TiO2 layer mitigates the depolarization field, facilitating cooperative rumpling of surface and subsurface layers in a tail ...

Stacked Nanosheet Gate‐All‐Around Morphotropic Phase Boundary Field‐Effect Transistors

Advanced Science, EarlyView.
This study proposes a material design using ferroelectric‐antiferroelectric mixed‐phase HZO to achieve steep subthreshold swing and non‐hysteretic on‐current enhancement in morphotropic phase boundary field‐effect transistors (MPB‐FETs). For the first time, two‐stacked nanosheet GAA MPB‐FETs with optimized HZO are demonstrated, validating superior ...

Improving CO Oxidation Catalysis Over High Entropy Spinels by Increasing Disorder

Advanced Science, EarlyView.
This work demonstrates that changing configurational disorder can significantly improve catalytic activity and stability. A series of high entropy spinel oxides (HESOs) are synthesized using air‐stable molecular precursors to build crystal lattices atom‐by‐atom. Spinel oxide powders are extensively characterized with a variety of advanced methods (i.e.
