Computer studies on projected range due to few eV to keV cluster impacts

The time-evolutionary Monte Carlo simulation code DYACAT and the molecular dynamics simulation code have been applied to investigate the cluster effects on the projected range of (Au)₅₅ cluster impacts on Cu targets, changing the cluster energy from 10 eV/atom to 50 keV/atom. For high-energy incidence (>10 keV/atom), the projected range of cluster atoms is nearly equal to that of monatomic ions. For low-energy incidence (<10 keV/atom), the projected range of cluster atoms is much larger than that of monatomic ions due to the clear-the-way effect. For very-low-energy incidence (<30 eV/atom), the many-body effect plays an important role in the projected range. For the monatomic ion bombardment, it prevents monatomic ions from penetrating into the solid, where it restrains one of the clear-the-way effects for the cluster impact
