Two mechanisms for 4:3 domain-matching epitaxy in ionically bonded systems were suggested on the basis of an analysis of this system. The proposed mechanisms were termed the reconstruction mechanism and the antiphase boundary mechanism. The reconstruction mechanism involved the restricted movement of ions, and the concomitant formation of double-plane dislocations in the epilayer. In the case of the antiphase boundary mechanism, only single-plane dislocations were assumed to be produced. There was also an associated energy change, because the nearest-neighbor coordination was destroyed.
