Results of cathodoluminescence analysis applied to Mg ion-implanted GaN (left) and three-dimensional distribution of Mg atoms introduced into GaN as visualized by atom probe tomography (right).
In Gallium Nitride (GaN) implanted with a small amount of magnesium (Mg), NIMS succeeded for the first time in visualizing the distribution and optical behavior of the implanted Mg at the nanoscale which may help in improving electrical performance of GaN based devices. Some of the mechanisms by which introduced Mg
