Resonant Interlayer Coupling in NbSe2‐Graphite Epitaxial Moiré Superlattices

Advanced Materials, EarlyView.
Combining angle‐resolved photoemission spectroscopy and density functional theory derived calculations, this work reveals strong interlayer coupling and moiré replicas of the graphite π states in molecular‐beam epitaxy grown van der Waals heterostructures of monolayer‐NbSe2/graphite, with implications for its collective phases that form. Abstract Moiré

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

Advanced Materials, EarlyView.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

A Functional 2D Carbon Allotrope Combining Nanoporous Graphene and Biphenylene Segments

Advanced Materials, EarlyView.
The synthesis of a novel nanoporous graphene (NPG) is reported with biphenylene segments via thermal fusion of 12‐armchair porous graphene nanoribbons grown on gold surfaces. Characterization using STM, AFM, and DFT reveals low‐defect semiconducting behaviour and tunable band gaps.

Ultrafast Terahertz Field Control of the Emergent Magnetic and Electronic Interactions at Oxide Interfaces

Advanced Materials, EarlyView.
Intense single‐cycle THz electric‐field pulses enable ultrafast control of emergent electronic and magnetic states at LaNiO3/CaMnO3 interfaces. Combined X‐ray and optical probes reveal sub‐picosecond demagnetization driven by spin‐polarized currents and slower magnetoelastic dynamics linked to spin–lattice coupling.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Non‐Destructive Laser Nanopatterning of Superconducting Heterostructures in Topological Sn Thin Films

Advanced Materials, EarlyView.
We demonstrate successful fabrication of high‐quality α‐Sn/β‐Sn planar nanostructures with arbitrary shapes by focused laser irradiation on topological Dirac semimetal α‐Sn thin films. The irradiated regions transform into atomically smooth, superconducting β‐Sn with a critical temperature of 3.7 K.

Successive Orthorhombic Distortions in Kagome Metals by Molecular Orbital Formation

Advanced Materials, EarlyView.
Orthorhombic distortions in kagome metals break the symmetry required for exotic charge order. Synchrotron X‐ray diffraction of NdRu3Si2 reveals successive orthorhombic transitions driven by molecular orbital formation between kagome layers. The frustrated kagome lattice hosts degenerate patterns of kagome dimers whose short‐range correlations produce ...

Magnetic Domain Texture in Fe3O4 Thin Films on SiO2 Nanospheres

Advanced Materials, EarlyView.
Fe3O4 thin films grown on ordered SiO2 nanospheres form curved nanocaps with 3D geometry, inducing magnetic domain texture. X‐ray spectromicroscopy (XMCD‐PEEM), cross‐sectional electron microscopy (STEM), and polarized grazing‐incidence small‐angle neutron scattering (GISANS) reveal how topography modulates magnetization.
