Anisotropy diffusion in monolayer growth of Au on Cu (110) by kinetic Monte Carlo method

Abstract

Morphological and Structural transitions during epitaxial growth of surface and interface are an important nanoscal phenomena. Understanding the diffusion of adatom in anisotropic surface on the fcc (110), presents a challenge because of the various processes and energy activation of diffusion. During monolayer formation, adatoms could aggregate and forming islands. the stability of these latter is related the its shapes and adatom bonding. In this work, we used the Kinetic Monte Carlo method, implementing anisotropic bond-breaking model (ABBM) to simulate the evolution of anisotropic islands. In order to discuss the monolayer growing, many parameters are taken into account such as potential barriers, temperatures, deposition rates at fixed coverage of 10% monolayer.
