Oxide-nitride heteroepitaxy for low-loss dielectrics in superconducting quantum circuits

This paper demonstrates that heteroepitaxial γ\gamma-Al2_2O3_3 grown on TiN via pulsed laser deposition forms a high-quality, single-crystal dielectric with an intrinsically low two-level system loss of (2.8±0.1)×105(2.8 \pm 0.1) \times 10^{-5}, establishing it as a promising materials platform for reducing dielectric losses in superconducting quantum circuits.

Energy level alignment of vacancy-ordered halide double perovskites

This study utilizes non-empirical hybrid functional calculations to validate the electronic properties and surface stability of lead-free Cs2_2MX6_6 vacancy-ordered double perovskites, revealing that CsX-terminated surfaces avoid detrimental in-gap trap states and identifying specific candidates with optimal energy level alignment for next-generation optoelectronic applications.

Robust Flat Magnetoresistivity in D03_3-Fe3_3Ga Driven by Chiral Anomaly

This study identifies D03_3-Fe3_3Ga as a topological flat-band semimetal where tilted Weyl points arising from flat-band crossings drive robust chiral-anomaly-dominated transport, including ultra-low-temperature non-Fermi-liquid behavior and an exceptionally stable flat magnetoresistance persisting up to 33 T.

Role of surface states and band modulations in ultrathin ruthenium interconnects

Using density functional theory, this study demonstrates that surface states fundamentally dictate the thickness-dependent resistivity of ultrathin ruthenium interconnects, where vacuum-terminated surfaces exhibit decreasing resistivity with reduced thickness while oxygen-terminated surfaces show the opposite trend, underscoring the critical role of surface engineering in optimizing next-generation device performance.

Phonon Signatures of Near-Room-Temperature Phase Transition in Quasi-One-Dimensional Bi4I4 Topological van der Waals Material

This study demonstrates that polarization-resolved Raman spectroscopy can detect subtle, stacking-driven structural rearrangements and their associated topological phase transition in quasi-one-dimensional Bi4I4 near room temperature, even in the absence of a change in global crystallographic symmetry.

Long-range interaction effects on the phase transition, mechanical effect, and electric field response of BaTiO3 by machine learning potentials

This study demonstrates that while a long-range MACELES model significantly improves the quantitative accuracy of predicting transition temperatures, elastic constants, and dielectric constants for BaTiO3 compared to a local-only model, both approaches successfully reproduce the material's key qualitative ferroelectric behaviors such as phase transitions and polarization switching.

Atomically Reconfigurable Single-Molecule Optoelectronics

Using scanning tunnelling microscopy-induced luminescence, researchers demonstrate that vertically displacing the central metal atom in a single phthalocyanine molecule allows for deterministic, atomic-scale tuning of its transition dipole moment to actively switch emission on or off and engineer tunable excitonic interactions in molecular assemblies.
