High pressure treatment of nanocrystalline GaN leads to transformations In its połytype strueture. A simple model of introduction of stacking faults by random shifts of OOlh planes was used for simułation of strain-mduced ₌ disordering process in nanocrystals.

It is caused by structural transformation: stacking faults evolution.
