It was noted that, by considering all of the various possibilities, a mapping scheme could be developed for the operation of super-dislocation sources in superlattices; depending upon the magnitude of the antiphase boundary energy. When the latter was extremely high, undissociated super-dislocations with giant Burgers vectors could act like a single Frank-Read source. When the antiphase boundary energy was low enough to permit dissociation, cooperative glide sources could operate. When the antiphase boundary energy was even lower, cooperative glide sources were expected to operate. At extremely low antiphase boundary energies, a single Frank-Read source could operate so as to generate a super-dislocation loop; while generating large amounts of antiphase boundary area.
