The production of single‐phase GaN , which is important for the realization of optoelectronic devices, is intricated by the existence of two polytypes (α‐GaN hexagonal, β‐GaN cubic, metastable). Both the orientation of the interface between teh cubic matrix and the polytypic hexagonal inclusion and the influence of the specific nature of the interface on the stability of the transformed polytype are of fundamental importance for the phase transformation of β‐to α;‐GaN.
