First stage of nucleation of GaN on (0001) sapphirege growth gives rise to islands which are randomly rotated and relaxed with misfit dislocations. The islands that start to coalesce from 60s growth time keep this random orientation and this leads to the bending of 60° misfit dislocations in the interface plane to form .-type TDs inside low angle boundaries.

Strain relaxation in (Al,Ga)N/GaN heterostructures≤70%), the second relaxation step is cracking. When cracked, relaxation of the films occurs by the introduction of long and straight .-type dislocations and small bowed .-type dislocation half-loops bordering the cracks. These two relaxing features lead for Al.Ga.N films above 2μm thick to full relaxation.
