Molecular dynamics and thermodynamic simulations of segregation phenomena in binary Au-Ag nanoparticles
A.G. Bembel Tver State University DOI: 10.26456/pcascnn/2017.9.081 Abstract: A complex approach combining atomistic molecular dynamics (MD) and thermodynamic simulations was applied to predict segregation in binary Au-Ag nanoparticles consisting of 2000 atoms (of about 4 nm in size). Both approaches predict the surface segregation of Ag ...
