| Outline of Final Research Achievements |
Solar energy-driven water splitting is receiving considerable interest in hydrogen production as a renewable energy source. We have reported a new technique to synthesize low cost GaN powder under moderate condition, Li3N or LiNH2 were used as a high reactive solid nitrogen source to improve the reaction rate and lowering the reaction temperature. In this report we studied the method to synthesize GaN : ZnO and GaN : InN solid solution powders by the use of these solid nitrogen sources. GaN : ZnO solid solution was successfully synthesized. Anodic photocurrent was clearly observed for the paste electrodes with GaN : ZnO solid solution and this observation indicates that the GaN : ZnO solid solution synthesized in this study shows n-type semiconductivity.
GaN : InN solid solution was also successfully synthesized by the reaction with GaCl3, InCl3 and LiNH2.
