Outline of Final Research Achievements |
Gallium nitride have attracted much attention as power semiconductor devices. Fabrication of metal-insulator-semiconductor structure is one of the key issues for GaN power devices. We investigated oxidation of gallium nitride (GaN) to form gallium oxide (GaO) insulator by super critical water oxidation as well as thermal oxidation. It was revealed that GaO formed by thermal oxidation was improved by the super critical water annealing while direct oxidation by super critical water was difficult.
