Abstract

Hematite (α-Fe ₂O ₃) nanowires were synthesized by the thermal oxidation of Fe-Ni alloy grids at 900 °C. The effects of hydrogen (H ₂) plasmas on the morphology and field emission properties of hematite (α-Fe ₂O ₃) nanowires were investigated. Many nanocrystallites with sharp tips were found to be produced on the surface of the originally smooth nanowires after H ₂ plasmas treatment. Field emission measurements demonstrated that the treated a-Fe203 nanowires possessed much better performance with turn-on field of ∼3.7 V/μm at 0.1 μA/cm ² of current density, compared with the as-grown samples.
