Laser Annealing of Transparent ZnO Thin Films: A Route to Improve Electrical Conductivity and Oxygen Sensing Capabilities

This study demonstrates that ultra-short-pulse laser beam scanning effectively enhances the electrical conductivity and oxygen sensing capabilities of Spatial Atomic Layer Deposition (SALD)-grown ZnO thin films on soda-lime glass, achieving a resistivity reduction of three orders of magnitude through optimized laser parameters while preserving structural integrity.

Kinematical and dynamical contrast of dislocations in thick GaN substrates observed by synchrotron-radiation X-ray topography under six-beam diffraction conditions

This study demonstrates that synchrotron-radiation X-ray topography under six-beam diffraction conditions, leveraging the super-Borrmann effect to penetrate thick ammonothermal GaN substrates, enables the quantitative determination of dislocation Burgers vectors and the observation of kinematical-to-dynamical diffraction transitions for nondestructive defect analysis.

Comparing the latent features of universal machine-learning interatomic potentials

This paper systematically analyzes the distinct latent feature representations learned by universal machine-learning interatomic potentials (uMLIPs), revealing significant cross-model differences, dataset-dependent trends, persistent pre-training biases after fine-tuning, and a method for compressing atom-level features into global structure-level descriptors.

Transition from Population to Coherence-dominated Non-diffusive Thermal Transport

This paper presents a Wigner Transport Equation-based framework to model non-diffusive thermal transport driven by both phonon populations and coherences, predicting significant size-dependent thermal conductivity deviations in low-conductivity materials like CsPbBr3_3 and La2_2Zr2_2O7_7 at experimentally accessible length scales.

Device-area selection of memristive transport regimes in epitaxial Hf0.5Zr0.5O2Hf_{0.5}Zr_{0.5}O_{2}-based ferroelectric devices

This study shows that epitaxial Hf0.5_{0.5}Zr0.5_{0.5}O2_2-based ferroelectric memristive devices exhibit coexisting area-dependent tunneling and localized-conduction regimes, with a statistical crossover at approximately 103 μm210^3~\mu\mathrm{m}^2 that correlates with the onset of ferroelectric wake-up and oxygen-vacancy redistribution.

Electronic Signature of Melting Onset in Polycrystalline Copper at Extreme Conditions

Using single-shot terahertz spectroscopy and molecular dynamics simulations, researchers demonstrate that the onset of melting in polycrystalline copper produces a distinct electronic signature—a transient increase in conductivity caused by the suppression of grain-boundary scattering—thereby revealing a close coupling between ionic disorder and electronic relaxation in nonequilibrium laser-driven matter.
