中文摘要 | we report a new method for large-scale production of gamnn nanowires, by annealing manganese-gallium oxide nanowires in flowing ammonia at high temperature. microstructure analysis indicates that the gamnn nanowires have wurtzite gan structure without mn precipitates or mn-related second phases. magnetism evolution due to nitrogen doping in manganese-gallium oxide nanowires was evaluated by magnetic measurements. magnetic measurement reveals that the magnetization increases with the increase of nitrogen concentration. ferromagnetic ordering exists in the gamnn nanowires, whose curie temperature is above room temperature. luminescence evolution was investigated by the cathodoluminesence measurement for a single nanowire and photoluminescence measurement in a temperature range between 10 and 300 k. experimental results indicate that optical properties can be modulated by nitrogen doping in manganese-gallium oxide nanowires.
