Beschreibungen/Notizen

• Using molecular-dynamics computer simulation, we study the processes occurring in a-Si after irradiation with a projectile with energy E 0⩽500 eV. By comparing Au and Si impact, we can study the effects of high and low deposited energy density. We find that damage production (creation of over- and under-coordinated Si atoms) and recoil implantation are strongly enhanced under Au impact. This effect can be traced back to the creation of an elastic collision spike for Au impact.
