The electron field emission from carbon nanotubes on nanocrystalline diamond films was investigated. Carbon nanotubes and nano-diamond films were deposited on Si substrates by hot filament chemical vapor deposition. The experimental results showed that the carbon nanotubes on nanostructured films exhibited a lower value of the turn-on electric field than those of carbon nanotubes and nano-diamond. It was found that the turn-on field of nanotubes on nano-diamond was about 0.9V/μm, which was lower than those of carbon nanotubes and nano-diamond.

AbstractCarbon nanotubes are attractive candidates for electron field-emitters due to their high aspect ratio, mechanical stability, and electrical conductivity. It has previously been shown that an electron beam hitting the tip of a carbon nanotube biased near the threshold of field-emission can stimulate the emission of a large number of electrons from the nanotube tip. Here we report on similar experiments on arrays of free-standing multi-walled carbon nanotubes (nanotube forests) interacting with a scanning electron microscope's primary beam. Electron gains of up to 19,000 were obtained. This can enable applications such as electron detection and multiplication, and vacuum transistors.

Nanocrystalline diamond field emitters were deposited by microwave plasma-enhanced chemical vapor deposition using porous Si as host matrixes. Scanning electron microscopy observations showed that the nuclei of diamond occurred at the edges of the etched pores, and the nanoscale diamond grains were partly embedded into the pores of the porous Si. The structure was beneficial to the electron field emission. The electron emission became more stable and the emission current was significantly enchanced comparing with those of the diamond films deposited on Si substrates scratched by diamond powder.
