Obtaining Composite Nanoparticles via Electron Beam Irradiation and Modeling the Processes of their Formation by Means of Molecular Dynamics

Abstract

The partial pressure of vapors of silicon and such metals as silver, copper, and tantalum is estimated and Ag–Si and Ta–Si systems are modeled thermodynamically. Nanoparticles of two types (core–shell and Janus-like) are obtained experimentally via high-temperature gas-phase synthesis using a direct-action electron accelerator. Characteristic features of the formation of composite nanoparticle structures are revealed by means of molecular dynamics, based on modified embedded-atom potentials.
