Molecular dynamics study of the relaxation processes induced by defects in metals

Radiation Damage in Metals

“…An atom will be displaced from its lattice position, if the transferred energy is larger than the sum of the formation energies [17,18] of a vacancy (E F V ∼ 1 eV) and an interstitial atom (E F I ∼ 4 eV). However, the displacement energy E d needed to move the interstitial outside the spontaneous recombination volume of its own vacancy is significantly larger than the reversible formation energy of a Frenkel defect.…”
