Atomic-scale order enables high thermal boundary conductance at β\beta-Ga2_2O3_3/4H-SiC interfaces

This study demonstrates that restoring atomic-scale order at β\beta-Ga2_2O3_3/4H-SiC interfaces preserves interfacial phonon coherence to achieve a record-high thermal boundary conductance of 231 MW m−2^{-2} K−1^{-1}, validated by both advanced computational modeling and experimental measurements.

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.

Hole concentrations in doped gray {\alpha}-Sn on InSb and CdTe measured with infrared ellipsometry

Using infrared ellipsometry, researchers determined the temperature-dependent heavy hole concentrations in 30 nm gray α\alpha-Sn layers grown on InSb and CdTe, revealing that substrate surface preparation induces n-type or p-type doping via ion diffusion while nearly intrinsic samples align with degenerate Fermi-Dirac statistics.

Facet-dependent Chemical Kinetics Governed Growth of Twisted Graphene Layers with Pre-designed Angles

This study presents a scalable chemical vapor deposition strategy to synthesize twisted graphene layers with pre-designed angles on platinum substrates by leveraging facet-dependent chemical kinetics and substrate reconstruction to control graphene orientation, folding, and tearing.

Flat-band energy filtering in interacting systems: conditions for improving thermoelectric performances

This study demonstrates that optimal thermoelectric performance in flat-band systems requires finite hybridization with dispersive states rather than perfect isolation, and highlights that electron-electron interactions significantly renormalize band structures, necessitating beyond-mean-field treatments for accurate predictions of the figure of merit.

Persistence of large and gate-tunable anisotropic magnetoresistance in an atomically thin antiferromagnet

This study demonstrates that the anisotropic magnetoresistance (AMR) in the atomically thin antiferromagnetic semiconductor NiPS3 remains robust down to 1.3 nm and is fully gate-tunable, enabling precise electrical readout and control of the Néel vector for advanced spintronic applications.
