| Реферат: | eng: The simulation of peculiarities of the surface layer reconstruction in the crystallites of aluminum after the ion bombardment and the copper film irradiated by the electron beam is carried out. The performed calculations are based on the molecular dynamics method. It is shown that the orientation of the irradiated surface and preliminary elastic deformation have a significant impact on features of atomic structure formation in the ion-modified layer in aluminum. Weak structural changes in the surface layer are observed at the irradiation of the {100} surfaces. Sufficiently great number of stacking faults is formed under irradiation of the {111} and {110} surfaces. It is shown that heating by the electron beam of the {110} surface in the copper film leads to the formation of stacking faults. It is shown that the preliminary elastic deformation of the material lowers the energy of the irradiation, at which formation of structural defects and fragmentation of crystallites of aluminum and copper will take place. |
