This first-principles study predicts carrier transport and spin relaxation in bulk germanium without empirical parameters, revealing that compressive biaxial strain can enhance hole spin lifetimes by up to two orders of magnitude through strain-induced valence-band splitting and suppressed spin mixing.
This study investigates stress-induced martensitic transformations in epitaxial Ni-Mn-Ga thin films and demonstrates how substrate strain and film thickness govern structural changes, which in turn drive significant evolution in the films' electronic structure and magneto-optical properties.
This study utilizes molecular dynamics simulations to demonstrate that adding 10% rhenium to polycrystalline tungsten enhances pre-instability plasticity and alters crack-tip dislocation mechanisms, thereby identifying atomistic indicators for the high-rate ductile-to-brittle transition while clarifying that these findings do not directly predict experimental transition temperatures.
This paper demonstrates that employing specific nonlocal perturbations, particularly moving oxygen atoms to alter aluminum coordination numbers, followed by local relaxation, significantly accelerates the exploration of potential-energy landscapes in amorphous AlO compared to conventional Monte Carlo methods, thereby reducing trapping in local minima and improving structure-search efficiency.
This paper presents a computational method that leverages Brillouin-zone sampling and force-difference unfolding in modest supercells to accurately determine dilute-limit atomic displacements and configuration coordinate diagrams for semiconductor defects, overcoming the size limitations of traditional first-principles calculations.
This paper reviews the evolution from high-entropy ceramics to the broader class of compositionally complex ceramics (CCCs), highlighting how non-equimolar designs, structural ordering, and microstructural engineering enable superior property tailoring beyond the capabilities of traditional equimolar solid solutions.
This study utilizes photoelectron spectroscopy to demonstrate that while the band gaps and exciton binding energies of picene and phenacene thin films are largely independent of molecular size and orientation, their ionization energies and electron affinities exhibit significant orientation-dependent shifts of approximately 1 eV driven primarily by electrostatic interactions from molecular quadrupole moments.
This paper demonstrates that a polymer filling which attracts colloids and extends beyond mesopores can paradoxically enhance both the rate and selectivity of colloid permeation, offering a physical explanation for nuclear pore complex function and a design strategy for advanced separation and delivery devices.
The paper introduces uMOF, a comprehensive resource comprising the largest DFT dataset for metal-organic frameworks (MOFs), a literature-mined experimental benchmark, and two universal machine learning interatomic potentials that significantly outperform existing models in predicting complex gas adsorption properties by leveraging diverse training data and high-level theory.
This paper proposes a unified microscopic framework for lead-halide perovskites, arguing that their unique combination of soft, anharmonic lattice dynamics and robust band-like carrier transport arises from a thermally fluctuating ensemble of locally symmetry-broken configurations driven by the Pb 6s² lone pair, which simultaneously dictates electronic structure, dielectric response, and defect tolerance.
