مستخلص: Simulations of the growth process of quasicrystal and square crystal lattice have been performed by the canonical Monte Carlo method. By varying the deposition rate and dimensionless temperature, the conditions for obtaining defect-free single crystal were investigated. The two-dimensional Penrose pattern was adopted as a model of the quasicrystal lattice where the positions of particles are restricted to the lattice sites and the interaction range between particles was assumed to be only within the nearest-neighbor distance. It was found that the diffusivity of quasicrystal was higher than that of square crystal lattice if attractive interaction was assumed. This tendency is opposite to that in the case of free particles. The conditions for obtaining a defect-free single crystal were that the deposition rate was low, under 6.57×10-6atom/(site MCS) and the dimensionless temperature was as low as possible but higher than that for polynuclear growth.
