Interfacial modulation of hump-like anomalous Hall effect in inhomogeneous SrRuO3 thin films
SrRuO3 (SRO) is a strongly correlated perovskite oxide known for its itinerant ferromagnetism, high electrical conductivity, and strong spin–orbit coupling. In this study, we grew epitaxial SRO (001)...
Emergence of anomalous Hall effect in Mn-doped kagome antiferromagnet FeSn thin films
Kagome magnets provide a fertile platform for exploring the interplay between magnetic order and Berry-curvature-driven transport. Here, we report a systematic investigation of the structural, magneti...

n-Ga2O3/p-GaN heterojunction based photodetector devices are fabricated on Si-doped (2¯01)β-Ga2O3 epitaxial layers grown by pulsed laser deposition technique on p-type c-GaN/sapphire templates. These...
Photocurrent and photoluminescence mapping of Au/FA0.9MA0.1PbI3 junctions: Probing carrier diffusion and thermo-optical degradation
We present a combined photocurrent (PC) and photoluminescence (PL) imaging study of FA0.9MA0.1PbI3 perovskite thin films patterned with Au gold pads forming planar Schottky junctions. From these measu...
Pressure amplification in single-stage gas launchers via Mach-stem formation
We present a pressure amplifier that integrates with single-stage gas launchers and enhances the accessible range of sample pressure states. The design of the amplifier was guided by hydrodynamic simu...
Self-induced long-distance acoustic pulling in phononic crystal waveguides
Acoustic pulling provides an additional degree of freedom for precise acoustic manipulation in acoustofluidics, with applications in separation, assembly, and cell characterization. However, most curr...
Microscopic mechanisms of hydrogen depassivation at amorphous SiO2/Si interfaces
Hydrogen is widely employed to passivate the dangling bonds formed during the thermal oxidation of silicon, thereby improving the electronic quality of the SiO2/Si interface. However, such hydrogen-re...
Numerical analysis of over-banding effects on screening-current-induced strain and turn-to-turn contact in no-insulation REBCO pancake coils
In operational high-field magnets, no-insulation (NI) rare-earth barium copper oxide (REBCO) pancake coils are subjected to severe hoop tensile stresses generated by strong Lorentz forces. Moreover, s...

This paper explores the use of geometric features from single-component Chinese characters to design novel mechanical metamaterials, thereby opening new culturally inspired channels for metamaterials...
Predicted new 2D MoX3 (X = Ga, In, Tl) monolayer with giant magnetocrystalline anisotropy and near room-temperature antiferromagnetism
We predict new 2D MoX3 (X=Ga, In, Tl) monolayers using first-principles calculations. All MoX3 monolayers are structurally, dynamically, mechanically, and thermally stable, as evidenced by negative fo...
Radiation-induced segregation in dilute Fe–Cr: A rate-theory framework for the Cr enrichment–depletion transition at the grain boundary
Radiation-induced segregation (RIS) poses a significant challenge for ferritic Fe–Cr alloys under irradiation, as it can compromise mechanical integrity and increase susceptibility to intergranular co...
Intercalation-induced high-temperature multiferroicity with strong magnetoelectric coupling in 2 <i>H</i> -VSe2 bilayer
Two-dimensional (2D) materials with a coexistence of magnetic and ferroelectric (FE) orders (i.e., multiferroics) provide a promising approach to control magnetism by electric fields. However, 2D mult...
Superchiral field enhancement from chiral bound states in the continuum
Generally, achieving chiral bound states in the continuum (BICs) in achiral metasurfaces or photonic crystals (PCs) requires breaking the in-plane inversion (I) symmetry or up-down mirror (σz) symmetr...
