|COMPUTER SIMULATION OF SELF-ORGANIZING PROCESSES INDUCED BY LOW-ENERGY ION IMPACT IN THIN FILMS|
The present paper is aimed at studying nonlinear effects induced by interaction of low–energy ion beams in thin metal films. We showed by a computer simulation that nonlinear oscillations were excited in the system of coupled atomic oscillators in crystal lattices, which resulted in the formation of new collective long-lived instabilities. The formation of atomic clusters with irregular atomic rearrangements, running autosolitons, long–lived undamped oscillations in local ranges of thin films can occur. The specific kind of these new heterogeneous structures depends on the properties of the potential characterizing bonds between atomic oscillators and the magnitude of external influence. These effects cannot be neglected in studying the structure and surface topography of thin crystal films by scanning microscopy.
