TLDR
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.

First-principles-based embedded atom method for PdAu nanoparticles

TL;DR: In this article, an accurate embedded atom method (EAM) potential was developed and employed in the simulation of PdAu metal alloy nanoparticles, which was parameterized based on an extensive set of density functional theory calculations of metal clusters in addition to bulk alloy properties.

Effects of wettability on explosive boiling of nanoscale liquid films: Whether the classical nucleation theory fails or not?

TL;DR: In this paper, the authors study the effects of surface wettability on the explosive boiling of nanoscale liquid films using molecular dynamics simulations, and propose a critical film thickness to address the debate of whether the classical nucleation theory fails in nano-scale boiling.

Surface free energies of solid metals: Estimation from liquid surface tension measurements

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.
