Thickness‐Driven Modulation of Electronic Transport in SnSe2‐grown Films by Low‐Temperature Atomic Layer Deposition

Advanced Electronic Materials, EarlyView.
Low‐temperature ALD enables scalable growth of SnSe2 films with precise thickness and crystallinity control, essential for nanoelectronics. Using a reactive Se precursor, films transition from nearly defect‐free single crystals (∼20 nm) to polycrystalline (∼100 nm) with thickness, directly impacting transport properties.

Interplay Between Structure and Interfacial Interactions in Fe‐Gd Synthetic Ferrimagnets

Advanced Electronic Materials, EarlyView.
Synthetic ferrimagnets with nearly identical Gd–Fe compositions but different architectures and crystallinity were investigated by element‐resolved microscopy, structural analysis and atomistic spin simulations. The results show that Curie temperature and domain evolution are governed primarily by structural order and interface quality, demonstrating ...

Effect of Gate Length Relative to Recess Coverage on the Performance of Enhancement‐Mode β‐Ga2O3 MOSFETs

Advanced Electronic Materials, EarlyView.
Gate‐length engineering in recessed‐gate enhancement‐mode β‐Ga2O3 metal‐oxide‐semiconductor filed effect transistors was investigated by extending the gate to fully cover the etched recess. Complete recess coverage improves electrostatic control, reduces series resistance, shifts the threshold voltage positively, and enhances mobility, on‐resistance ...

Zinc Grid Based Transparent Electrodes for Organic Photovoltaics

Advanced Energy Materials, EarlyView.
A transparent flexible electrode based on an embedded zinc grid with ≈1 µm linewidth is reported, and its utility as a drop‐in replacement for indium‐tin oxide coated glass electrodes in organic photovoltaic devices is demonstrated. The zinc grids are fabricated using the unconventional approach of condensation coefficient modulation, using a ...

Combining ToF‐SIMS and Multivariate Analysis to Resolve Active Sites on Ni‐Based HER Catalysts

Angewandte Chemie, EarlyView.
Time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), combined with principal component analysis (PCA) and multivariate curve resolution (MCR), disentangles ultrathin mixtures of Ni, NiO, and Ni(OH)2 on model Ni electrodes. By revealing a hydroxide‐specific ion marker linked to hydrogen evolution reaction (HER) activity, the method offers a new ...

M–O–C Catalysts: Copper Single Atoms Supported on Oxocarbon Covalent Networks as Electrocatalysts for Glycerol Oxidation to Formic Acid

Angewandte Chemie, EarlyView.
We introduce a new class of single‐atom electrocatalysts based on oxygen‐coordinated metal sites embedded in oxocarbon networks (M–O–C), alternative to traditional M–N–C materials. A Cu–O–C catalyst derived from oxocarbon precursors exhibits highly dispersed Cu single atoms and delivers faster glycerol oxidation kinetics and higher formate selectivity ...

Decoding Gas Evolution Pathways and Interfacial Chemistry in Layered Oxide Cathodes for Safer Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.
