• The origin of field emission from a specific nano-diamond/carbon nanowall (ND/CNW) electron emitter, which has high and stable field emission characteristics, was examined by field emission spectromicroscopy and scanning electron microscopy. It was found that graphite sticks are present on the field emission sites of the films. Energy distribution curves of electrons field-emitted from the specified sites have the same features as those field-emitted from a metallic substance (graphite). Thus, it was concluded that graphite sticks present on the ND/CNW film are responsible for the field emission.
