COMPUTER-SIMULATION OF 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 calculated as a function of time under various conditions of atomic binding energy, temperature and deposition rate. The Monte Car lo method based upon the solid-on-solid model was utilized for the pre sent calculation. We found a geometrical restriction on the growth fro nt of grains in the 2D Penrose pattern, which is also expected for the growth of an actual quasicrystal.
