Using scanning tunneling spectroscopy and continuum model calculations, this study reveals that electrostatic disorder and structural relaxation are critical in breaking symmetry and shaping the electronic structure of marginally twisted bilayer MoS, explaining unexpected energy differences between stacking regions.
This study employs first-principles density functional theory to analyze the crystal structures of antiperovskite oxides containing tetrel and alkaline earth elements, demonstrating how tolerance factors predict their structures and how cation ordering can induce ferroelectricity, while also revealing unique electronic trends driven by significant antibonding interactions.
This study utilizes ultrabroadband photoconduction microscopy and simulations to demonstrate that shallow trap states, specifically Ga-Ga-In oxygen vacancy defects located ~0.32 eV below the conduction band, rigidly control the electrical performance of amorphous InGaZnO thin-film transistors, enabling accurate prediction of transfer characteristics from defect density measurements.
This paper reports the first successful epitaxial growth of high-quality single-phase FeGe thin films on Al2O3 substrates, which exhibit a Néel temperature of 397 K and transport anomalies near 100 K potentially linked to charge density waves, thereby establishing a versatile platform for investigating CDW mechanisms and antiferromagnetic spintronics applications.
This study employs first-principles calculations and machine learning to reveal that the ultralow lattice thermal conductivity in vacancy-ordered Cs double perovskites stems primarily from intrinsically weak chemical bonding leading to low sound velocities, rather than the rattling phonon modes typically associated with their structural voids.
This paper demonstrates and theoretically explains a room-temperature, helicity-dependent circular ratchet effect in two-dimensional tellurene, where the inherent chirality of its atomic chains enables the rectification of terahertz radiation into a direct current that can be reversed by switching the light's helicity.
This study reports the detailed physical properties of high-quality RhGe and CoGe B20 single crystals, revealing their metallic, paramagnetic, and weakly correlated semimetal nature to establish a platform for investigating multifold fermions and helicoid-arc surface states in chiral topological semimetals.
This paper investigates the spectroscopic properties of a new -doped sesquisulfide single crystal, identifying 26 luminescence transitions across the 0.49 to 5.5 m range and confirming their assignments through theoretical calculations, thereby establishing the material as a promising low-phonon host for broad mid-IR laser applications.
This study reports the successful growth of undoped and Tl/In-doped bulk crystals via the miniaturised vertical Bridgman method, characterizing their structural homogeneity, congruent melting behavior, and enhanced luminescence properties that closely resemble their doped caesium iodide counterparts.
This study utilizes multi-dimensional photoemission spectroscopy and configuration-interaction analysis to demonstrate that LaCoO3 undergoes a thermally driven spin-state crossover from a predominantly low-spin ground state to a mixed low-spin/high-spin configuration, with Co 2p photoemission identified as a sensitive quantitative probe for tracking this transition.
