COMPUTER-SIMULATION OF GROWTH-PROCESS OF BINARY QUASI-CRYSTAL

We performed Monte Carlo simulation of the aggregation process of a tw o-component Lennard-Jones system on the two-dimensional (2D) Penrose l attice for the purpose of studying the details of the creation and gro wth process of quasi crystals. We adopted the potential parameter valu es proposed by Widom et al. [Phys. Rev. Lett. 58 (1987) 706]. The pres ent simulation clarified that the stability of the formed quasi crysta ls depends on temperature and the strength of the potential and that t he transition from solid state to liquid state occurs when the value o f the inverse of the dimensionless temperature is approximately 4.0.
