Abstract
A method of examining matching faces of vacuum-cleaved gold-decorated rocksalt has been used to study nucleation behavior. It has been shown that there is no site for site correspondence between nuclei on the two surfaces even if the surfaces are given identical treatments and are not heated above 150 °C. Rearrangement of many of the surface steps occurs if the surfaces are heated above 150 °C. If one surface is exposed go air after cleavage, most of the surface features are completely changed.
