Revealing Intrinsic Functionalization, Structure, and Photo‐Thermal Oxidation in Hexagonal Antimonene

Small, EarlyView.
Cross‐sectional electron microscopy reveals that antimonene hexagons exhibited inner defects and protective organic functionalization against oxidation. Temperature and power‐dependent Raman spectroscopy on varying thicknesses of FLA hexagons show that thinner flakes (<20 nm) exhibited a blueshift and intensity decrease, contrasting with the redshift ...

Liquid‐Phase Fabrication of Janus 2D Materials: Defect‐Rich MoS2 Ultrathin Layers Asymmetrically Decorated with Au Nanoparticles

Small, EarlyView.
This work presents a versatile strategy for asymmetrically decorating MoS2 flakes using SiO2 microspheres as masking templates. The Janus MoS2 exhibits a 1.9‐fold enhancement in photoluminescence (PL) due to the incorporation of Au nanoparticles (NPs), primarily dominated by B exciton emission, which is attributed to defect‐rich structures.

Bandgap Engineering On Demand in GaAsN Nanowires by Post‐Growth Hydrogen Implantation

Small, EarlyView.
The GaAsN bandgap in the GaAs/GaAsN core–shell nanowire shifts to lower energy for increasing N concentrations. By post‐growth H implantation the GaAsN bandgap is moved to a higher GaAs‐like energy through the formation of N–H complexes. By thermal annealing, these complexes can be partially dissolved, allowing to tune the GaAsN bandgap over a range of

Symmetric Metal Organic Framework‐Plasmonic Architectures for Reversible and High‐Sensitivity Optical Sensing

Small, EarlyView.
This work presents a plasmonic sensing platform combining surface lattice resonances (SLRs) in 2D metal nanoparticle gratings with ZIF‐8 MOF films. The plasmonic grating is easily and scalably produced from template‐assisted assembly of metal colloids, which is fully compatible with MOF growth. The resulting MOF‐plasmonic structure allows for a dynamic

Electrospun PAN Membrane Loaded with AgInP2Se6 Nanosheets for Triboelectric Energy Harvesting

Small, EarlyView.
Exfoliated AgInP2Se6 nanosheets are incorporated into a polyacrylonitrile (PAN) polymer matrix by electrospinning and applied for the first time in a triboelectric nanogenerator (TENG). The hybrid membrane delivers strong electrical output and exhibits reversible humidity sensitivity, responding rapidly to changes in relative humidity.
