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 and second-nearest neighbor interactions. When the bond energy ratio of second-nearest neighbor to first-nearest-neighbor interactions was 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 was ~0.25, the ridge side face of a tabular shape had the {100}/{100}/{111} structure instead of the {111}/{111} re-entrant edge. In spite of disappearance of the re-entrant edge, the side face had a higher growth rate than the top face because the {100} face still grows faster than the {111} face.
