Effect of Substrate Temperature on Nanoparticles Growth Simulation by Metropolis Algorithm

Authors

Abstract

  In this paper, nucleation stage and bulk growth of deposited nanoparticles are simulated by Monte Carlo method. Temperature effect is applied on nucleation and bulk growth processes by metropolis algorithm. Our results showed that the number of islands decreases and following size of Island increases by increasing substrate temperature. Also, a coalescence phenomenon is observed at higher temperatures. At 400 K, due to the phenomenon of surface diffusion and particles mobility, particles grow in thin columnar structures and are separated from each other.
