Designing Defect Structure and Interfacial Strain in an Epitaxial VN Bilayer Film by Tailoring N Concentration

Advanced Materials Interfaces, EarlyView.
The N concentration in an epitaxial VN bilayer is tailored from overstoichiometric V0.49N0.51 to understoichiometric V0.56N0.44. Based on ab initio, diffraction, and microscopy data, the overstoichiometric V0.49N0.51 layer contains V vacancies, N Frenkel pairs, and a high density of dislocations.

Influence of Metal Oxide Interface Layers on the Thermochromic Properties of VO2 Thin Films Deposited by Magnetron Sputtering

Advanced Materials Interfaces, EarlyView.
This study investigates the thermochromic properties of VO2 deposited on aluminum doped zinc oxide precoated fused silica with Al2O3, TiO2, and WO3 as interface layers. The results indicate that the metal‐to‐insulator transition is highly influenced by the grains formed at the interface.

Tailored Nickel Oxide Interfacial Layers Unlock Enhanced Charge Dynamics in LaTiOxNy Thin Film Photoanodes

Advanced Materials Interfaces, EarlyView.
This study highlights the importance of designing photoanode architectures for solar water splitting that align intrinsic material properties with functional interfaces to optimize the extraction of photogenerated charges. The incorporation of NiOx surface layers in LaTiO2.5N0.5 (LTON) thin film photoanodes exemplifies this approach by leveraging band ...

Multimodal Imaging of Strain and Light Emission of Core–Shell InGaN/GaN Wires under a Sub‐Micrometer Polychromatic X‐Ray Probe

Advanced Materials Interfaces, EarlyView.
Micro‐Laue diffraction and excited optical X‐ray luminescence are used to study InGaN/GaN core‐shell wires on the BM32 beamline at the European Synchrotron. Multimodal imaging of X‐ray fluorescence, deviatoric strain tensors and optical emissions is performed using simultaneous mapping.

Molecular Engineering for Enhanced Second‐Order Nonlinear Response in Spontaneously‐Oriented Evaporated Organic Films

Advanced Optical Materials, EarlyView.
Intramolecular bridge‐locking frustrates detrimental anti‐parallel packing in evaporated organic films. This design enhances net polar orientation, leading to a twofold off‐resonance increase in the second‐order nonlinear susceptibility (χ(2)) without electric‐field poling.
