This study reveals that while the structural stability of 2D MoWS alloys is primarily composition-driven, their electronic and optical properties, including band-edge splitting, valley energetics, and optical selection rules, are critically governed by the specific microscopic arrangement of atoms across the full composition range.
This paper introduces an environment-dependent tight-binding framework that augments Slater-Koster hopping integrals with bond-screening functions, fitted to ab initio pseudo-atomic orbital Hamiltonians across multiple configurations to generate transferable, large-scale electronic structure models with ab initio precision.
This study introduces a machine learning-driven pathfinding algorithm based on the Crystal Normal Form to map diffusionless transformation pathways and analyze the kinetic persistence of metastable TiO polymorphs by correlating potential energy landscape topography with experimental phase stability.
This study employs Density Function Perturbation Theory to comprehensively characterize the infrared, Raman, piezoelectric, and elastic properties of ultra-wide band gap Mg-IV-N\textsubscript{2} (IV = Si, Ge, Sn) semiconductors, including their vibrational modes, phonon dispersions, and tensor properties within the Pna2\textsubscript{1} crystal structure.
Using molecular dynamics simulations, this study reveals that the transition from antiplasticization to plasticization in chitosan-water mixtures is governed by the connectivity of dynamically accessible free volume regions, which modulates the competition between weakened polymer-polymer and enhanced polymer-water interactions to dictate the material's elastic properties.
This study reveals that electroforming in Pt/NbOx memristors induces a previously unrecognized, highly correlated redistribution of oxygen and platinum, where localized Joule heating drives the formation of a Pt-rich filament alongside an oxygen-enriched pathway, challenging the conventional view of noble metal electrode inertness.
This study utilizes a vicinal Cellular Automata model to demonstrate that the morphological transition from meandered patterns to mound structures on crystal surfaces is governed by the competition between Ehrlich-Schwoebel barriers and adatom mobility, revealing a reversible pathway between these distinct growth regimes across varying deposition and diffusion conditions.
This paper demonstrates a scalable method for significantly reducing the thermal conductivity of silicon membranes through block copolymer self-assembly and controlled nanohole etching, validated by a novel three-probe technique that overcomes thermal contact resistance challenges to achieve a fivefold reduction in thermal conductivity at room temperature.
This study combines in situ experiments and phase-field simulations to reveal a rich diversity of melting patterns in lamellar eutectics, identifying key physical mechanisms and scaling behaviors that depend on melting velocity and initial microstructure spacing.
This paper proposes a simplified free-energy framework that establishes a theoretical thermodynamic maximum for solar energy conversion at approximately 74%, while acknowledging that practical limits like the Shockley-Queisser limit (~33%) and specific processes such as spontaneous emission and nonradiative losses currently constrain achievable efficiencies to lower values.
