In this work, Molecular Dynamics (MD) simulations are performed to study the smoothing of a rough Al(111) surface by means of metal cluster impact. A projectile Al13 cluster impinges on an island-shape defect supported over the surface at incident angles of 15°, 45° and 90°, and with the initial kinetic energy being varied from 1 to 40 eV/at. Depending on the angle and the initial kinetic energy, several phenomena take place, from projectile sticking and island flattening to fragmentation and sputtering with substrate damage for the largest energies.
