This study reports the design and characterization of two new 2D layered hybrid perovskites, (C15H16N)2CdCl4 and ((Br)C15H15N)2CdCl4, which exhibit record-high photoluminescence quantum yields originating from their organic trans-stilbene cations, demonstrating their potential for efficient radiation detection and scintillation applications.
This study demonstrates that ion implantation induces a metal-insulator transition in epitaxial ScN thin films through a two-stage damage accumulation process involving isolated acceptor defects at low doses and carrier-localizing point defects at high doses, with the transition threshold and localization strength critically dependent on the initial film quality and substrate.
This paper develops a unified quantum master equation model to systematically analyze and compare the efficiency of microcavity OLEDs across weak and strong light-matter coupling regimes, aiming to identify the optimal strategy for overcoming performance limitations like efficiency roll-off.
This paper introduces a dynamic extension of the high-temperature expansion to accurately compute the dynamic structure factor for frustrated quantum spin systems, successfully benchmarking the method on various models and reproducing experimental data for the S=1 pyrochlore material NaCaNi2F7.
This paper extends high-temperature series expansions to dynamic Matsubara spin correlators for Heisenberg models, providing precomputed exact expansion coefficients up to the 12th order for arbitrary lattices to enable the calculation of static susceptibilities and real-frequency dynamic structure factors.
This paper presents a gauge-invariant theoretical framework to compute the average density of Bloch electrons in a homogeneous magnetic field up to second order, revealing that while the linear response for insulators follows the Streda formula, metals exhibit an additional Fermi-surface contribution from orbital magnetic moments, and the second-order response is significantly influenced by the quantum metric tensor generating a pseudo-magnetic moment.
This study successfully stabilizes bilayer nickelates with smaller A-site ions through entropy engineering, revealing that the resulting chemical pressure enhances structural distortions and interlayer coupling, which projects a superconducting transition temperature exceeding 100 K.
This paper introduces PVK-LLM, a domain-knowledge-guided framework that integrates Large Language Models with hierarchical Bayesian Optimization to autonomously discover a novel, high-efficiency perovskite solar cell recipe achieving over 26.0% power conversion efficiency, thereby overcoming the limitations of general LLMs in navigating complex material design spaces.
This study employs a Deep Potential-based machine learning molecular dynamics framework to reveal that high-concentration LiTFSI electrolytes induce rapid, anion-derived SEI growth with superior stability compared to the slower, LiF-dominated interphases formed in lower-concentration or LiPF6-based systems, thereby providing quantum-accurate insights into electrolyte-dependent SEI nucleation mechanisms in lithium metal batteries.
This paper presents a scalable fabrication method for vertical Nb/graphene/Nb Josephson junctions using a freestanding van der Waals membrane architecture that enables double-sided metal deposition without exposing oxidation-sensitive interfaces, resulting in high-quality devices with reproducible supercurrents and clear superconducting characteristics.
