Abstract
Simulation of heteroepitaxial growth with high lattice mismatch is rep orted. The dynamics of layer growth is treated using the Monte Carlo t echnique and the energetics aspects related to the effect of strain ar e accounted for in the VFF approximation. It is shown that the surface becomes rough and 3D islands, showing (111) facets, appear. The strai n relaxation is shown to be almost complete after a few atomic layers. Formation of point and extended defects is observed in the deposited layers. (C) 1998 Elsevier Science S.A.
