[HTML][HTML] Theoretical evaluation of electronic density-of-states and transport effects on field emission from n-type ultrananocrystalline diamond films
In the nitrogen-incorporated ultrananocrystalline diamond [(N) UNCD] films, representing an
n-type highly conductive two-phase material comprised of sp 3 diamond grains and sp 2-rich
graphitic grain boundaries, current is carried by a high concentration of mobile electrons
within large-volume grain-boundary networks. Fabricated in a simple thin-film planar
form,(N) UNCD was found to be an efficient field emitter capable of emitting a significant
amount of charge starting at the applied electric field as low as a few volts per micrometer …
