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

Defect Engineering in Large‐Scale CVD‐Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics

Small, EarlyView.
The controlled formation of defects in large‐area CVD‐grown hBN using various irradiation methods is demonstrated. Defect type and properties depend on particle type (He+, Ne+, Ar+, neutrons, and electrons), substrate effects, and film thickness.

Highly Selective Photocatalytic Degradation of Organic Pollutants by ZnO@C Core–Shell Nanoparticles Via Superoxide Radical Pathway

Small, EarlyView.
This study investigates a novel two‐step synthesis of ZnO@C nanoparticles (NPs), featuring enhanced photocatalytic dye degradation via selective superoxide (O2•−) radical generation under visible light. The precisely engineered carbon shell uniquely improves light–matter interaction and visible‐light absorption, as well as facilitates efficient charge ...
