The effect of the relative growth rate between {111} and {100} faces on the growth morphology of perfect and twinned face-centered-cubic crystals was investigated with a Monte Carlo simulation considering both first-nearest-neighbor (FNN) and second-nearest-neighbor (SNN) interactions. When the bond energy ratio of SNN to FNN interactions is close to zero, the {111} twin planes make a reentrant edge, which enhances the growth rate on this plane, leading to a tabular growth shape. When the ratio is similar to 0.25, the ridge side face of a tabular shape has the {100}/{100}/{111} structure instead of the {111}/{111} reentrant edge. In spite of disappearance of the reentrant edge, the side face has a higher growth rate than the top face because the {100} face still grows faster than the {111} face. (C) 2003 Elsevier Science B.V.
