Electric‐Field‐Assisted Spin Coating: A New Process for Adjusting Crystallization of Perovskite Thin Films

Advanced Materials Technologies, EarlyView.
Electric‐field‐assisted spin coating is introduced as a wet‐film processing route for guiding perovskite crystallization. A transient perpendicular field produces distinct structural maxima rather than monotonic grain growth: largest scanning electron microscopy (SEM)‐derived grain size at nominal 2 kV cm−1${\rm cm}^{-1}$, largest X‐ray diffraction ...

Residual Tetramethylammonium Hydroxide Limits ZnO Nanoparticle‐Based Quantum Dot Light‐Emitting Diode Performance

Advanced Optical Materials, EarlyView.
Residual tetramethylammonium hydroxide (TMAH) from ZnO nanoparticle (NP) synthesis is uncovered as a hidden impurity that migrates into quantum dot emissive layers during thermal processing. The resulting exciton quenching reduces the efficiency of quantum dot light‐emitting diodes despite improved electron transport upon annealing.

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

Advanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.
