| Outline of Final Research Achievements |
In this study, we attempted to create GaNSb, an anion-controlled nitride alloy, towards high hole concentration and low resistive p-type nitride semiconductors by increasing an energy level of valence band maxima. We obtained up to 1% Sb content in GaNSb and smooth GaNSb surfaces even grown at low temperature, 800 oC. However, it is found that Sb resulted in poor PL intensity of GaInN QWs, then we have decided not to use Sb source in the MOVPE reactor. Instead, we have obtained low temperature p-side structures by using tunnel junctions and low temperature grown n-GaN, showing a reasonable device resistance.
