Atomistic Simulations of Pure Tin Based on a New Modified Embedded-Atom Method Interatomic Potential
Publikováno v:
Metals, Vol 8, Iss 11, p 900 (2018)
A new interatomic potential for the pure tin (Sn) system is developed on the basis of the second-nearest-neighbor modified embedded-atom-method formalism. The potential parameters were optimized based on the force-matching method utilizing the densit
