COMPUTER-SIMULATION OF THE FILM GROWTH-PROCESS ON THE 2-DIMENSIONAL PENROSE PATTERN

We performed computer simulation of the film growth process on the two -dimensional (2D) Penrose pattern, which is considered a typical struc tural model of quasicrystal. The atomistic structure of the deposited atoms was obtained as a function of time under various conditions of a tomic binding energy, temperature and deposition rate. The Monte Carlo method based upon the solid-on-solid model was utilized for the prese nt calculation. We found a geometrical restriction on the growth front of grains in the 2D Penrose pattern, which is also expected for the g rowth of an actual quasicrystal.
