Abstract

A molecular-dynamic simulation of the behavior of unclosed nanostructures obtained by self-scrolling of nanosized bilayer Ni-Cu films with different internal structure compositions is performed. In the course of selfscrolling of a nanosized film in the absence of any external action, its edges undergo weak decaying harmonic oscillations. Peculiar effects of the initial film internal structure on the oscillation characteristics are found out. It is shown that by varying the initial film composition or saturating it with structure defects, one can deliberately change the oscillation amplitude or frequency, or both of them simultaneously. The layer composition is changed in such a manner that the geometrical dimensions of the simulated nanostructure remain practically unchanged. The observed peculiarities are appealing for research and development of accessories and hardware for nanodevices of different types and applications.
