Abstract EN
Coalescence induced by deposition of different Cu clusters on an epitaxial Co cluster supported on a Cu(001) substrate is studied by constant-temperature molecular dynamics simulations.
The degree of epitaxy of the final system increases with increasing separation between the centres of mass of the projectile and target clusters during the collision.
Structure, roughness, and epitaxial order of the supported cluster also influence the degree of epitaxy.
The effect of energy and temperature is determinant on the epitaxial condition of the coalesced cluster, especially both factors modify the generation, growth and interaction among grains.
A higher temperature favours the epitaxial growth for low impact parameters.
A higher energy contributes to the epitaxial coalescence for any initial separation between the projectile and target clusters.
The influence of projectile energy is notably greater than the influence of temperature since higher energies allow greater and instantaneous atomic reorganizations, so that the number of arisen grains just after the collision becomes smaller.
The appearance of grain boundary dislocations is, therefore, a decisive factor in the epitaxial growth of the coalesced cluster.
