Electron field emission from transparent multiwalled carbon nanotube sheets for inverted field emission displays
Strong, conducting, transparent carbon nanotube sheets were prepared by solid-state draw from well-ordered, aligned multiwalled carbon nanotube (MWCNT) forests [Zhang et al., 2005] [1]. Study of electron field emission from such transparent MWCNT sheets shows threshold fields of less than 0.5 V/lm with current densities high enough for display applications. Step-like field emission current incr...
متن کاملDemonstration of Field Emission Cathode Operation in a Plasma Environment
Field emission cathodes are being considered for use on low-power electrostatic and electromagnetic propulsion systems as well as on electrodynamic tether systems. In these systems, field emission cathodes prevent negative spacecraft charging by emitting a lowpower electron beam that is accommodated by the ambient plasma. Prototype cathodes were tested at the University of Michigan as part of a...
متن کاملExperimental Characterization of a Carbon Nanotube Field Emission Cathode
There is interest in the use of carbon nanotubes (CNTs) to create a field emission cathode. The primary benefit of this cathode is that a gas flow is not required to create electrons, which is of critical importance for space missions that must minimize propellant mass. A field emission cathode consisting of CNT arrays is fabricated by the Georgia Tech Research Institute and the Georgia Tech Hi...
متن کاملFabrication of carbon nanotubes field emission cathode by composite plating.
Carbon nanotubes (CNTs) have high aspect ratio and have great potential to be applied as the field emission cathode because of its large field enhancement factor. In this work, a high performance carbon nanotube field emission cathode (CNTFC) was fabricated by using a composite plating method. The CNTs were purified by acid solutions and then dispersed in electrobath with nickel ions at tempera...
متن کاملNanoengineering of Materials for Field Emission Display Technologies
The holy-grail in terms of flat panel displays has been an inexpensive process for the production of large area ‘hang on the wall’ television that is based on an emissive technology. As such electron field emission displays, in principle, should be able to give high quality pictures, with good colour saturation, and, if suitable technologies for the production of the cathodes over large areas w...
