Computer Simulation of Atomic Displacement Cascades in Solids

  • I. M. Torrens
  • M. T. Robinson


Atomic displacement cascades originating from primary atoms displaced with energy up to 100 keV have been investigated by computer simulation. The model includes inelastic energy loss and finite temperature effects. Results obtained for crystals of copper, iron and gold indicate that long-range channeling and focusing are rare. The numbers of vacancies created and of those remaining are both directly proportional to the primary energy corrected for inelastic loss over the energy range up to 100 keV. The number of clusters of i vacancies is in constant ratio to the number of clusters of (i – 1) vacancies, this ratio being independent of primary energy.
