Description:

(abstract)

In Mg ion implantation doping of GaN, sequential N ion implantation reportedly changes Mg concentrations in the Mg ion-implanted region and the underlying region after activation annealing. Our atomic-resolution analyses showed that, in the Mg ion-implanted region, the N ion implantation increases the concentration of MgGa. The rest of the Mg atoms agglomerated to form clusters on the extended defects, and its concentration was also increased by the N implantation. The N implantation affected the coarsening of the defects, which cause Mg cluster formation.
