Abstract

The molecular dynamics method using an empirical potential energy function to describe the Sisingle bondGe interaction used to study the different stages of the growth of Ge on silicon (001) substrates. We have determined the minimum energy adsorption sites for single Ge adatoms and for two Ge adatoms. In addition, we have also calculated the activation energy for the Ge atoms to undergo surface diffusion. We also present results of simulations of a fraction of monolayer of Ge. The critical thickness for the stability of a pseudomorphic film of Ge is also considered.
