This study employs density functional theory to comprehensively investigate the structural, electronic, mechanical, optical, and thermoelectric properties of the trigonal LaBiO perovskite, revealing its wide indirect band gap, ductile nature, and potential for photovoltaic, optoelectronic, and thermoelectric applications.
This study employs density functional theory with various exchange-correlation functionals to investigate the electronic energy structure, effective carrier masses, and fundamental optical properties of the InCdI compound.
This paper provides a concise overview of pyroelectricity for students and engineers, tracing its historical discovery from ancient observations to modern crystallographic descriptions while explaining the physical principles, mathematical definitions, and distinctions between primary and secondary effects that underpin its application in infrared detectors and ferroelectric materials.
This study experimentally validates process-microstructure-property relationships in bainitic steels by correlating three-dimensional phase-field simulations of microstructural features with multiaxial yield strength, demonstrating how optimized thermal processing can refine microstructures and enhance mechanical performance.
Despite employing divergent exploration strategies and encountering a common-mode error related to incomplete structures, sixteen autonomous scientific agents converged on the same optimal materials frontier for methane storage, demonstrating that independent agents can yield robust conclusions from shared inputs while also replicating shared biases.
This study demonstrates that indium-catalyzed molecular beam epitaxy enables the growth of high-quality, single-phase (010) (AlxGa1-x)2O3 films with a thermal conductivity twice that of previously reported values by suppressing defect scattering, while also characterizing the subsequent decline in thermal properties due to alloy scattering and interface stiffening.
Using atomistic models trained on first-principles data, this study reveals that compositional disorder in relaxor PMN generates a continuum of polar vibrational excitations and a boson peak of quasi-localized modes, which collectively explain the material's simultaneous crystalline order and glass-like dielectric, optical, and thermal responses.
This paper proposes a computationally efficient machine learning interatomic potential training strategy that utilizes a small dataset derived from limited DFT calculations on small supercells, combined with multi-size defect and pristine bulk data, to accurately predict point defect properties in large-scale systems with minimal error.
Contrary to the prevailing belief that vacancy aggregation causes NV- decoherence, this cluster-correlation-expansion study demonstrates that aggregating vacancies into multi-vacancy complexes actually extends spin coherence times by 2.7 to 4.4 times compared to isolated vacancies, as the resulting fine-structure splitting and symmetry-induced frequency mismatches suppress the spin-exchange dephasing mechanism.
By employing scanning three-dimensional X-ray diffraction and symmetry-adapted analysis, this study reveals that ferroelastic domain walls in the hybrid improper ferroelectric CaSrTiO are intrinsically extended structures characterized by a continuous rotation of the tilt order parameter through a tetragonal intermediate, challenging conventional models of ferroic interfaces.
