Abstract: Abstract The morphology of isolated crystals and polycrystalline films can thoroughly be influenced by twin nucleation. In order to obtain more insight into this rather complicated subject a new theoretical concept, called the nucleation surface, is introduced and worked out quantitatively. The nucleation surface on a given position of a crystal facet is proportional to the probability that the given position is overgrown by a twin, which has nucleated at an earlier time. It is calculated in detail for {111} <111> penetration twins on diamond facets, as a function of the position on the {111} plane and of the geometrical parameter α = √3 ν100/ν111. The analytical and numerical results show that the twin abundance depends strongly on both parameters. The calculations account well for a number of experimental observations.
