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