“…For less well characterised electrode surface, the phenomenology appears to be different. 16,17 An enhanced field emission is observed with significant current values even at low electric fields. It seems that the current emission is enhanced by local microscopic emitting sites, which can be micro-protrusions on surfaces 18 or chemically modified surfaces by doping or local deposits.…”

“…FEAs coated with a SiC thin layer with doping of Er and Pr to improve emission properties. 3) Field emission from fickle micropowders included in diesel exhaust clearly showed that some types of microparticles act as good field emission sources. 4) SiC powders are widely used in industries as polishing materials such as grinders and sandpaper, and are inexpensive.…”

Field emission characteristics of a cathode consisting of SiC micropowders with sharp edges were examined. Emission current from the cathode followed the Fowler–Nordheim relationship; therefore, it was confirmed that the SiC micropowders acted as the field electron source. A field enhancement factor of ∼1000 was obtained. This value was comparable to that of conventional emitters. A good short-term stability of the fluctuation in the emission current from the cathode, which was less than 7% of the total emission current, was determined.

“…a and b parameters depend on Φ and are estimated as: a = 1.54 × 10 −6 A m −2 , b = 6.83 × 10 9 V −1/2 m For our materials, Fowler-Nordheim's law must be modified to take into account the enhanced field emission at local emission sites on surface. 4 Such phenomenon is observed when significant current values exist even for low electric fields. It is supposed that the current emission is enhanced by local microscopic emitting sites as small protrusions.…”
