Nanoscale origin of thermal anisotropy in monoclinic \texorpdfstring{β\beta-Ga2_2O3_3}{beta-Ga2O3}

By combining advanced thermal spectroscopy techniques with first-principles calculations, this study reveals that the pronounced thermal anisotropy in monoclinic β\beta-Ga2_2O3_3 originates from high-frequency, short-mean-free-path phonons, whereas low-frequency phonons remain nearly isotropic and attenuate directional contrast at macroscopic scales.

Nano-ARPES observation of a flat band at the \bar{M} point in 2.4{\deg} twisted bilayer graphene

This paper reports the first direct observation via nano-ARPES of an unexpected flat band at the Mˉ\bar{M} point, far from the Fermi level, in 2.4° twisted bilayer graphene, highlighting the necessity of probing the entire Brillouin zone to fully capture electronic states in twisted structures.

Structural characterization of the rutile-GeO2/TiO2 (001) heterointerface

This study utilizes high-resolution transmission electron microscopy to characterize the structural and chemical properties of rutile-GeO2/TiO2 (001) heterointerfaces, revealing that growth temperature dictates whether the interface is amorphous or epitaxial, with the latter accommodating a ~4% lattice mismatch through specific dislocation networks and thermally driven substrate faceting.

Strontium Titanate Capping Layers as Kinetic Regulators of Redox Phase Transitions in Oxide Heterostructures

This study demonstrates that few-nanometer-thick strontium titanate capping layers act as active kinetic regulators of redox phase transitions in oxide heterostructures by controlling oxygen diffusion rates, thereby enabling precise tuning of phase transition temperatures through adjustments in capping-layer thickness and oxygen partial pressure.

Low-energy collective electronic excitations in a gold monolayer

Using time-dependent density functional theory, this study reveals that a free-standing gold monolayer (goldene) supports three unexpected, anisotropic, low-energy plasmonic branches arising from the hexagonal shape of its single-band Fermi surface, which enables the conversion of single-particle excitations into collective charge oscillations despite the system's seemingly simple electronic structure.

Unifying Low-Frequency Raman and Infrared Signatures across Perovskites

This study employs machine-learning-based molecular dynamics to unify the understanding of low-frequency Raman and infrared signatures across diverse perovskite classes, revealing that polar off-centering enhances dielectric responses while nonpolar octahedral tilting drives Raman central peaks, thereby linking spectral features to the symmetry, coupling, and dynamics of underlying lattice instabilities.

Thermoelectric properties and modulation doping of ultrawide-bandgap nitride monolayers

This study combines first-principles calculations and transport modeling to predict that composition-tunable ultrawide-bandgap Bx_{x}Al1−x_{1-x}N and Bx_{x}Ga1−x_{1-x}N monolayers exhibit high thermoelectric figures of merit (ZT > 2.5) and identify candidate modulation-doping partners and intrinsic breakdown fields, suggesting their potential for advanced thermoelectric and high-field power-electronic applications.

Order-Disorder in Fe-Si Alloys: Implications for Seismic and Transport Properties of Earth's Inner Core

This study utilizes first-principles molecular dynamics and thermodynamic modeling to demonstrate that chemical ordering in iron-silicon alloys under inner-core conditions governs phase stability, elastic anisotropy, and thermal conductivity, suggesting that metastable disordered cubic Fe-Si phases could explain key seismic and transport anomalies in Earth's inner core.
