We developed a ReaxFF force field for silicon carbide (SiC), specifically parametrized to capture complex, temperature-dependent vapor compositions during sublimation. ReaxFF molecular dynamics (MD) simulations of crystalline SiC at 3000–4500 K revealed a diverse range of vapor species─including SiC2, Si, Si2C, Si2C2...

Because nanoscale roughness strongly influences carrier scattering, phonon transport, and domain stability in SnSe-based electronic and energy devices, these results provide a chemistry-guided framework for morphology control in layered chalcogenide thin films.

To extend the study of vanadium disulfide (VS2) nanostructures beyond the system size and simulation time limits of ab initio methods, we introduce a new ReaxFF parameter set: ReaxFF VS2-2025. The ReaxFF VS2-2025 potential was parametrized against extensive quantum mechanical and experimental data, and it can accurat...

To predict the thermochemistry and thermophysical properties and oxidation mechanisms of titanium diboride (TiB2), we have developed a ReaxFF reactive force field in which the parameters are trained against a set of quantum mechanics data, including the heats of formation and elastic properties for various titanium b...

Bridging atomically precise materials design with scalable membrane manufacturing remains a central challenge in separation science. Two-dimensional covalent organic frameworks (2D COFs) offer tunable porosity and chemistry, but poor crystallinity and processability have limited their performance in membranes. Here we...
