Growth _–Fe2O3 nanowires with different crystal direction of iron film


Keywords: ,

–Fe2O3 nanowires (NWs) were synthesis from different crystal direction of iron film by thermal oxidation in oven. The crystal direction of iron film was successfully control by sputtering 50 nm iron on different direction of MgO substrate. The directions of MgO substrate were (100), (110) and (111). The crystal direction of coated iron film would follow the direction of the MgO. The NWs were fabricated on the direction of (110) and (111) iron film for 10 hours at 350 oC. The –Fe2O3 NWs with the diameter of 10–30 nm and 1 m in length were observed. The –Fe2O3 film was formed on the direction of (100) iron film after thermal process. The samples were observed and analyzed by field emission scanning electron microscopy (FE–SEM), transmission electron microscopy (TEM) and X–ray diffraction (XRD).
