“…Field emission devices based on carbon nanotubes (CNTs) displayed remarkable emission characteristics and a good current stability because of the high-aspect-ratio and electrical conductivity of CNTs, as well as the mechanical stiffness of the nanotubes [11][12][13][14][15]. Park and co workers [16][17][18][19][20][21][22][23][24] have demonstrated that by incorporating multi-wall CNTs directly into the microplasma devices, it is possible to reduce the ignition voltages by 14-18%.…”

Microplasma was produced in argon gas in a scanning electron microscope at near-atmospheric pressure using a multi-wall carbon nanotube (CNT) film as a cathode. It is demonstrated that with the CNT film used as a cathode, the breakdown voltage was much lower than the breakdown voltage when the conventional cathode made of flat metal film was used and the discharge was highly reproducible. These features of the gas discharge are defined by the field emission from the CNT cathode.

“…Though CNTs have repeatedly shown impressive field emission performance, such as high emission current densities and low turn-on electric fields 8,[14][15][16][17][18][19][20][21][22] they are plagued by burn-out issues. CNT burn-out -the removal of individual CNTs due to the over-emission of current inducing Joule-heating and subsequent structural deformation and eventual removal -is exacerbated by the use of screen printed CNT pastes which form spaghetti-like mats of varied height.…”

Here we present our on-going efforts toward the development of stable ballasted carbon nanotube-based field emitters employing hydrothermally synthesized zinc oxide nanowires and thin film silicon-on-insulator substrates. The semiconducting channel in each controllably limits the emission current thereby preventing detrimental burn-out of individual emitters that occurs due to unavoidable statistical variability in emitter characteristics, particularly in their length. Fabrication details and emitter characterization are discussed in addition to their field emission performance. The development of a beam steerable triode electron emitter formed from hexagonal carbon nanotube arrays with central focusing nanotube electrodes, is also described. Numerical ab-initio simulations are presented to account for the empirical emission characteristics. Our engineered ballasted emitters have shown some of the lowest reported lifetime variations (< 0.7%) with on-times of < 1 ms, making them ideally-suited for next-generation displays, environmental lighting and portable x-rays sources.

“…Over the past few years, the study of carbon nanotubes (CNTs) as electron-emission cathodes for large area panel displays has become a new research hot-point for researchers [1][2][3][4][5][6][7]. Researchers around the world are now striving to obtain a higher emission current density, larger emission area and lower threshold field [8].…”
