MOLECULAR DYNAMICS SIMULATION OF DEFECT FORMATION IN IRRADIATED SOLIDS
D. ŞOPU, M. A. GÎRŢU

Abstract. We present the results of molecular dynamic simulations of collision cascades in copper irradiated with 500 eV ions. Simulations for up to 3 000 fs showed that the total number of defects and the number of double vacancies have a sharp increase to the maximum reached at about 900 fs, followed by a slow decrease. During the relaxation phase the amorphous regions resulted from local melting during the collision phase recrystallize.
