Abstract :
Nitrogen-doped gallium phosphide nanowires were directly synthesized via a sublimation of ball-milled powders under ammonia flow. The average diameter of the nanowires is 40 nm and the length is about 500 μm. They consist of single-crystalline zinc blende structured crystals with the [1 1 1] growth direction. The photoluminescence shows the typical isoelectronic bound exciton peaks in the range 2.1–2.25 eV. The concentration of the doped nitrogen atoms is estimated to be about 1018 cm−3.
