A consistent set of embedding functions and pair interactions for use with the embedded-atom method was determined empirically by fitting to the sublimation energy, equilibrium lattice constant, elastic constants, and vacancy-formation energies of the pure metals and the heats of solution of the binary alloys as discussed by the authors.Abstract:
A consistent set of embedding functions and pair interactions for use with the embedded-atom method [M.S. Daw and M. I. Baskes, Phys. Rev. B 29, 6443 (1984)] have been determined empirically to describe the fcc metals Cu, Ag, Au, Ni, Pd, and Pt as well as alloys containing these metals. The functions are determined empirically by fitting to the sublimation energy, equilibrium lattice constant, elastic constants, and vacancy-formation energies of the pure metals and the heats of solution of the binary alloys. The validity of the functions is tested by computing a wide range of properties: the formation volume and migration energy of vacancies, the formation energy, formation volume, and migration energy of divacancies and self-interstitials, the surface energy and geometries of the low-index surfaces of the pure metals, and the segregation energy of substitutional impurities to (100) surfaces.read more

TL;DR: In this paper, the nucleation of particles from a supersaturated iron vapor is investigated by molecular dynamics simulations, where the supersaturated IMV is embedded in an argon heat bath which removes the heat generated during the IMV nucleation process.

Molecular dynamics simulations of reactive wetting
Edmund B. Webb,Gary S. Grest +1 more
TL;DR: In this paper, molecular dynamics simulations of liquid Ag drops spreading on a Cu(1/0/0) surface are studied with a mixture of liquid and liquid Ag. The radius of the Ag wetting layer increases initially as t 1/2 for both cases but drops spread faster in reactive systems.

TL;DR: In this paper, a semi-theoretical approach was proposed to estimate the surface energy of solids in the absence of direct experimental measurement. But this method was not suitable for the case of high-index surfaces.

Calculation of the surface segregation of Ni-Cu alloys with the use of the embedded-atom method
TL;DR: The surface composition of Ni-Cu alloys has been calculated as a function of atomic layer, crystal face, and bulk composition at a temperature of 800 K and the results show that the composition varies nonmonotonically near the surface with the surface layer strongly enriched in Cu while the near-surface layers are enriched in Ni.
