Abstract : A systematic experimental study of the kinetics of nucleation of gold vapor onto the (100) cleavage face of magnesium oxide was made over the temperature range from 209-381C in ultra-high vacuum. The degree to which preferred nucleation occurred was found to depend on the defect structure of the surface. The experimental results are in quantitative agreement with a nucleation model originally developed for a defect-free surface and extended in this study to account for the contribution of point defects.
