The dislocation annihilation in GaN epitaxy on Si was investigated by silicon delta-doping. The dislocations were bent at the delta-doping position at the segments lying on the basal plane, was shown by transmission electron microscopy (TEM) observations. The process was achieved via pining of dislocations at the basal plane by the silicon delta-doping was suggested by the studies.
