Abstract

With use of molecular dynamics method the kinematic characteristics of non-closed nanostructures were studied. Nanostructures were formed from bilayer nano-sized crystalline films of Ni-Cu grown on the substrate. Interatomic interactions were described within the embedded atom method. It was shown that in case of sudden separation from the substrate the edges of non-closed nanostructures can make free harmonic oscillations. The dependence of the amplitude of oscillations of the size of the original film was investigated. The influence of the crystallographic orientation of the original film on the parameters of oscillations of non-closed nanostructures was analyzed. The results of simulation are of interest in the design of the components of nanodevices for various applications.
