Physical model of the transition from a hexagonal to a cubic structure during growth of boron nitride under nitrogen and argon ion irradiation

A model based on original experimental data is proposed to describe the transition of the structure from hexagonal to cubic during the growth of boron nitride layers. It is postulated that boron and nitrogen ions entering the growing layer form additional atomic planes parallel to the (ab) planes of the hexagonal structure or complete existing dislocations in the growing crystal, causing the boron nitride to undergo a transition to a cubic structure.
