Abstract

Behavior of unclosed nanostructures is investigated in the course of their formation from bilayer films of a Ni-Cu system with crystal structure. The investigation is performed on the basis of the molecular dynamics method using a many-body potential of interatomic interaction. It is shown that the edges of an unclosed nanostructure produced from a bilayer metal film can perform free harmonic oscillations. The dependence of the oscillation amplitude of the nanostructure on the size of the initial film is investigated. Optimum geometrical parameters of the initial film are determined in order to form unclosed nanostructures oscillating with maximum amplitude. The results obtained are promising for the development of components for nanodevices of different types and applications.
