Abstract
Reactivity of synthetic diamond single crystals with liquid aluminium is very distinct for the different diamond faces. The {1 1 1} faces are barely attacked by liquid aluminium whereas the {1 0 0} surface atoms are easily dissolved and participate in the formation of carbides resulting in jagged {1 0 0} faces featuring a characteristic morphology which can be explained by the effect of dissolution-resistant small surface areas. By providing a third bond to the underlying atoms, these areas protect the atoms within a volume bounded by {1 1 1} faces.
