Stress-induced solid flow drives surface nanopatterning of silicon by ion-beam irradiation
Stress-induced solid flow drives surface nanopatterning of silicon by ion-beam irradiation
Ion Beam Sputtering (IBS) is known to produce surface nanopatterns over macroscopic areas on a wide range of materials. However, in spite of the technological potential of this route to nanostructuring, the physical process by which these surfaces self-organize remains poorly under- stood. We have performed detailed experiments of IBS …
