Zr2SN2 thin films are transparent across most of the visible range, show an average refractive index of 2.95, and exhibit degenerate n-type conductivity with carrier density above 10^20 cm-3 and mobility above 8 cm2 V-1 s-1.
Non-equilibrium growth kinetics produce anisotropic vanadium dopant distributions and associated localized tensile strain in WS2 monolayers.
A new polarizable QM/MM method for periodic systems uses SCME for water with multipoles up to hexadecapole and anisotropic polarizabilities, achieving full QM accuracy via careful near/far-field expansions and damping.
Nanopillar geometry activates otherwise suppressed optical transitions in SiC divacancy and NV centers by transforming the excitation polarization inside the sub-wavelength structure.
DFT survey of H, He, B, C, N, O, P, S at six CSL grain boundaries in ferritic iron finds B and C strengthen cohesion while He, O, S act as powerful decohesives, with public data release.
Thermally driven sliding in MoS2 moiré superlattices proceeds via domain-wall-mediated collective reconstruction with ultralow barrier rather than rigid translation, as shown by ML MD; 0.1% S vacancies induce pinning.
MD simulations with ML force fields reveal non-monotonic friction-load curves in MX2/metal heterostructures arising from coexistence of longitudinal, lateral-slip, and zig-zag sliding modes.
Fine-tuning ML interatomic potentials via a new LoRA-based Equitrain framework with minimal additional data improves phonon and thermal predictions over base and scratch-trained models in 53 systems.
First epitaxial Na2KSb films grown and their (111) surface electronic structure mapped via ARPES and DFT, showing termination-dependent states preserved after Cs/Sb activation.
Pressure increases the collinear AFM Neel temperature in NiBr2 to 100 K at 3 GPa while suppressing helimagnetic order above 0.8 GPa, with ab initio calculations attributing this to the second-nearest interlayer exchange j2'.
The work generalizes ALMO-EDA to periodic solids at the DFT level, decomposing lattice and interlayer energies into chemically intuitive frozen, polarization, and charge transfer contributions across molecular crystals, moiré heterobilayers, and layered perovskites.
A physics-informed autoencoder compresses 3D charge density into a 16x16x16x16 latent representation that, combined with MAGPIE descriptors, predicts bulk modulus, Young's modulus, shear modulus, formation energy, and Debye temperature with R2 values of 0.94, 0.88, 0.87, 0.96, and 0.89 on 6059 DFT-s
Nanostructure geometry on suspended van der Waals membranes provides deterministic control of multiaxial strain and bandgap profiles in 2D materials like Ga2Se2, with a two-component analytical model predicting shifts to within 12% error and extendable to other materials.
An agentic framework fusing large atomic and language models rediscovers 66 known superconductors and guides experimental verification of four new ones with transition temperatures from 2.5 K to 6.5 K.
pyzentropy implements recursive entropy to compute total system entropy from first-principles supercell calculations, reproducing Invar behavior and experimental phase diagrams for Fe3Pt.
High pressure converts IO3 units to hypercoordinated IO6 in K2Zn(IO3)4.2H2O forming 2D iodate networks, promotes multicenter O-H-O bonds, yields bulk modulus 22(3) GPa, and closes the band gap from 4.2 eV to 3.4 eV at 20 GPa.
The TAHM method approximates temperature-dependent conductivity by thermally averaging the square of the density of states near the Fermi level obtained from ab initio MD simulations on five test systems.
COGITO creates accurate tight-binding models from DFT that match MLWF accuracy while keeping the orbitals chemically interpretable and projected onto atomic centers.
Epitaxial DyTe_{2-δ} films on MgO show a Te-deficiency supercell attributed via DFT to Fermi surface nesting that periodically occupies the Te square net and opens a gap.
Ab initio DFT calculations find zinc vacancies and interstitials dominate defects in Zn3P2, producing p-type behavior via shallow acceptors, with Frenkel pair formation partially compensating conductivity and thermodynamically limiting n-type doping.
Binding sfTA produces bilayer binding correlation energies closer to twist-averaged CCSD than standard sfTA by incorporating binding interactions into twist-angle selection.
Pressure up to 15.6 GPa collapses the bandgap in 2H-MoTe2 into a semimetallic state, replacing variable-range hopping with weak localization and antilocalization while a phenomenological model unifies the magnetoresistance across regimes.
DFT predicts phase transitions in BaSnF4 at 10 GPa and 32 GPa; the first is confirmed experimentally while the second is supported by indirect signatures.
