Md. Rouhani et al., MONTE-CARLO SIMULATION OF MISMATCH RELAXATION AND ISLAND COALESCENCE DURING HETEROEPITAXIAL GROWTH, Thin solid films, 318(1-2), 1998, pp. 61-64
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.
