The potential is stiffened.

The potential was designed to simulate solidification in Cu. For simulation of solid properties, the version published in [M.I. Mendelev and A.H. King, Phil. Mag. 93, 1268-1278 (2013), KIM item https://doi.org/10.25950/34748b8d ] is better for this purpose. Other versions of this potentials with different SFE and USFE were published in: [M.I. Mendelev and A.H. King, Phil. Mag. 93, 1268-1278 (2013), KIM item https://doi.org/10.25950/34748b8d ], [V. Borovikov, M.I. Mendelev, A.H. King and R. LeSar, MSMSE 23, 055003 (2015)] and [V. Borovikov, M.I. Mendelev and A.H. King, MSMSE 24, 085017 (2016) KIM item https://doi.org/10.25950/e49bf93d ].

The potential was developed to simulate vitrification in the Cu64.5Zr35.5 alloy. Another model developed with improved fidelity to this vitrification process is [M.I. Mendelev, Y. Sun, F. Zhang C.Z. Wang and K.M. Ho, J. Chem. Phys. 151, 214502 (2019)], see https://openkim.org/id/MO_609260676108_000.

This potential is tabulated using more spline points to provide smoother cutoff and better accuracy for simulations.

This potential is only intended for the study of Cu diffusion on the Ag(111) surface.

All of the cross interactions are determined through a universal mixing function and not every combination of species has been tested. The database is not suitable for modeling metal compounds.

This potential is designed for the structural properties of High Entropy Alloys (HEA)s and Complex Concentrated Alloys (CCAs). The fitting procedure involved developing all included unary, binary and ternary systems so it can be used for any alloy subset. This potential focuses on the structural analysis of alloys including shear strength and elastic constants, dislocation dynamics and their impact on alloy strength, and the analysis of defect effects, such as voids, on material properties. However, the potential was not optimized for temperature-dependent properties and was not fit to density, thermal expansion coefficients, or thermal conductivity data.
