AB  - Nanostructures based on multiwalled carbon nanotubes (MWNTs) are fabricated using 
      plasma of the mixture of hydrogen and nitrogen gases. The plasma-sharpened tips 
      of nanotubes contain only a few tubes at the apex of the structure and lead to 
      the dramatic enhancement in the emission current density by a factor >10(6) with 
      the onset field as low as 0.16 V/microm. We propose that the nature of the 
      tunneling barrier changes significantly for a nanosize tip at very high local 
      electric field and may lead to the saturation in the emission current density.
