High pressure treatment of nanocrystalline GaN leads to transformations in its polytype structure. A simple model of introduction of stacking faults by random shifts of OOlh planes was used for simułation of strain-induced ■ disordering process in nanociystals. |

High pressure treatment up to S 20GPa in Diamond Anvil Celi (DAC) changes relative intensities of peaks, increases intensity between the peaks. It is caused by structural transformation: stacking faults evolution.
