Influence of Schwoebel barrier and diffusion anisotropy on step density oscillation amplitude during epitaxial growth

摘要

Speeding up of step density oscillations (SDO) damping on singular surface with Schwoebel barriers was demonstrated by Monte Carlo simulation. Estimation of Schwoebel barrier necessary for complete absence of SDO was carried out. Increase of atomic surface anisotropy was shown to be responsible for slowing down SDO damping and oscillations phase shift for anisotropy similar to anisotropy on (001) reconstructed surfaces.
