nanowires by ball milling process

Nov 15, 2019· In summary, FeGa 2 O 4nanowireswere obtained in Fe doped GaN powders after high-energyball millingfor 20 h and subsequently annealed at 1100 °C. DSC-TGA analysis demonstrates GaN: Fe decomposition at 1100 °C. TEM investigations show that thenanowiresare quite straight with diameters of about 50–60 nm and lengths up to 2 μm.
