Arrays of oriented silicon carbide (SiC) nanowires are synthesized by reacting stable carbon nanotubes—which act as both template and reagent—with SiO. Field emission measurements on the nanowires indie that the arrays are excellent field emitters, technologically useful field emission current densities being produced at very low electric fields.
