Popis: Ion implantation is a widely used doping technique for Si MOSFETs, but there have been few reports that demonstrate the formation of p-type GaN layer. We have succeeded to make the p-n junction by implanting Mg ions into n-type GaN layer, but Mg implanted layer showed inhomogeneity including p and n-type regions. Evaluation methods of homogeneity of Mg ion implanted GaN layer by mapping technique using current-voltage characteristics are demonstrated.
