Visualization ofke V-ion-induced spikes in metals

Abstract
Using gliding averages, the density, temperature, and pressure evolution in a keV-ion induced spike in copper is presented. The particular event visualized has been selected since it represents the average features of ion-beam induced mixing. Equilibration between potential and kinetic energy in the molten spike core is discussed, emphasizing the role of the latent heat of melting. Re-fueling of heat to the spike by condensing adatoms is exemplified.
