Search for one dimensional (1D) van der Waals materials has become an urgent need to meet the demand as building blocks for high performance, miniaturized, lightweight device applications. Polyyne, a 1D atomic chain of carbon is the thinnest and stro

Abstract The microstructures of the Ti–V alloy are studied by purely first-principles calculations without relying on any empirical or experimental parameter. The special quasirandom structure model is employed to treat the all-proportional solid s

The transition between gapped (semiconducting) and gapless (metallic) phases and tunability of bandgap in materials is a very lucrative yet considerably challenging goal for new-age device preparation. For bulk materials and for two-dimensional layer

Predicting alloy microstructures with parameter-free theoretical schemes remains a challenge. Here the authors derive a general phase field approach to reproduce the microstructural evolution of a nickel-aluminum alloy as a function of composition on

In the present work, we report different interlayer excitonic states of an aligned $\mathrm{Mo}{\mathrm{Se}}_{2}/\mathrm{Mo}{\mathrm{S}}_{2}$ incommensurate van der Waals (vdW) heterostructure (HS). The HS was fabricated by stacking chemical vapor de

Ti–6 wt% Al–4 wt% V (Ti64) is an α + β titanium alloy, in which the alloying components strongly affect the mechanical properties. In this report, element partitioning effects in Ti64 are investigated by using the first-principles phase field (

The effect of the Pt concentration on microstructures of Ti-Pt alloys is studied by the first-principles phase field (FPPF) method, which enables us to investigate the evolution of microstructures from first principles without using thermodynamic emp

Ni-Ti alloys around equiatomic composition, i.e., those with 45–55 at.% Ni, at 1200 K are studied by using the first-principles phase field (FPPF) method, which does not rely on any thermodynamic empirical parameter. There is an important tolerant
