Interlayer‐Mediated Stabilization of Metastable P63cm ScFeO3 on Al2O3

Advanced Materials Interfaces, EarlyView.
This work develops an interlayer‐mediated stabilization method, demonstrated by the deposition of the P63cm phase of ScFeO3 ‐a metastable polymorph that exhibits multiferroic and optical properties not possible in the ground state. Thin films of the P63cm phase of ScFeO3 are stabilized on (0001) Al2O3 by the spontaneous formation of two atomic layers ...

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

Advanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Wavelength‐Selective, High‐Speed, Self‐Powered Isotype Heterojunction n+‐ZnO/n‐Si Photodetector with Engineered and Tunable Spectral Response

Advanced Materials Technologies, EarlyView.
Wavelength‐selective ZnO/Si photodetectors, operating with no power supply. Engineering of the constituting materials converts them from white‐light sensitive to only NIR‐sensitive. When external power is applied, the wavelength selectivity of the devices can be tuned to different spectral ranges.

Enhanced Sensitivity in Low‐Energy Inverse Photoemission Spectroscopy with an Off‐Axis Parabolic Mirror for Efficient Light Collection

Advanced Materials Technologies, EarlyView.
This study presents an enhancement in the sensitivity of inverse photoemission spectroscopy (IPES) by more than 20 times by utilizing a custom‐made off‐axis parabolic mirror for improved light collection. Combined with ultraviolet photoemission spectroscopy (UPS), the enhanced sensitivity of our IPES setup allows for comprehensive mapping of interface ...

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue

Advanced Materials Technologies, EarlyView.
A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

Selective Directional Enhancement in Gold/Perovskite Quantum Dot Metasurfaces

Advanced Optical Materials, EarlyView.
A thin gold layer can selectively enhance the directional radiation of a perovskite quantum dot (QD)1D metasurface by incorporating hybrid plasmonic excitation and redistributing diffraction orders from substrate to cover. The use of template‐assisted self‐assembly techniques enables breakthrough tunability in radiative properties over large areas ...

Topological Line Defect Waveguide

Advanced Optical Materials, EarlyView.
The work unveils the prevalence of topological modes across diverse photonic crystal platforms by experimentally demonstrating topological transport in conventional line‐defect waveguides. Interfacial waveguides are utilized as mode convertors to selectively excite topological states in photonic crystal systems.

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking

Advanced Optical Materials, EarlyView.
Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies

Advanced Optical Materials, EarlyView.
A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.
