MOLECULAR-DYNAMICS SIMULATIONS OF SEQUENTIAL DEPOSITION OF METALLIC SUPERLATTICES

In this study the growth of Fe/Ag and Pd/Cu multilayers is investigate d by using a molecular dynamics simulation method. In-plane and out-of -plane motions of the deposited atoms are observed for temperatures in the range 10 K-330 K. Furthermore the film structure shows a remarkab le dependence on the deposition rate and temperature and these paramet ers may turn the growth from amorphous, or highly defective, to crysta lline with defective interfaces. In this transition, however, the type of atom to be deposited plays a primary role and in our study a remar kable propensity of Fe for amorphization has been observed.
