This paper reports the discovery of an ambient-pressure Dirac electron state in the organic conductor -(BETS)AuCl, which exhibits transport properties similar to high-pressure states in other materials and is identified via first-principles calculations as a quasi-three-dimensional massive Dirac semimetal, offering a new platform for studying bulk Dirac fermions without high-pressure requirements.
This paper presents a high-temperature, high-speed atomic force microscopy system utilizing a qPlus sensor, a specialized Quadpod scanner, and hybrid-loop frequency demodulation to achieve atomic-resolution imaging of molten metal/solid interfaces above 200°C, revealing distinct surface structures compared to room-temperature samples.
This study combines digital in-line holography and ultra-high-speed pyrometry with a kinetic-transport modeling framework to characterize and predict the solid-phase oxidation and melting time scales of single micron-sized iron particles, revealing distinct oxygen-concentration dependencies across different phase transition stages to advance metal-fuel combustion design.
This paper reports the successful fabrication and comprehensive temperature-dependent characterization of MOCVD-grown quasi-vertical AlN Schottky barrier diodes on bulk AlN substrates, demonstrating high current densities, stable rectification up to 300°C, and identifying Poole-Frenkel emission and an interfacial AlNxOy layer as key factors governing their carrier transport and leakage mechanisms.
This paper presents a Zr concentration-dependent sub-lattice phase-field model that successfully explains the ferroelectric-to-antiferroelectric transition in Hf1-xZrxO2 by capturing the competition between orthorhombic and tetragonal phases and revealing how intermediate Zr concentrations lead to mixed-phase states and gradual polarization switching due to local electric field variations.
This study utilizes density functional theory to reveal that the robust ferromagnetic insulating state in strained LaCoO₃ films arises from a unique ordered array of high-spin and low-spin Co³⁺ ions, where ferromagnetic superexchange interactions mediated by low-spin ions overcome competing antiferromagnetic forces to stabilize the ground state.
This study demonstrates that standard density functional theory and hybrid functionals often fail to accurately describe the electronic structure of 2D van der Waals ferroelectric -InSe bilayers and trilayers, necessitating a high-fidelity quasiparticle self-consistent GW approach implemented in the Questaal package to correctly predict properties like band gaps and polarization.
This study experimentally demonstrates that ultrathin MoOCl2 flakes serve as a promising building block for ultracompact, broadband quarter-wave retarders, overcoming the size and bandwidth limitations of traditional materials and metasurfaces through their giant optical anisotropy.
This paper introduces information entropy as a general-purpose collective variable for enhanced sampling that enables the unsupervised discovery of metastable states and reaction pathways across diverse molecular and condensed-phase systems without requiring predefined reaction coordinates.
This study introduces a materials-design framework for low-voltage pressure-sensitive electroadhesives using ion-containing bottlebrush elastomers that combine tunable conformability with on-demand reversibility, achieving significant adhesion enhancement at voltages below 2 V through mobile ion migration.
