Abstract :
Nitrogen containing carbon nanostructures for flat field emission cathodes were synthesized for 40 min in a high isostatic pressure apparatus where the gaseous pressure was 75 MPa and the heat zone temperature was 1500degC. The carbon-nitrogen nanomaterials deposited on graphite substrates were investigated by scanning electron microscopy and infrared spectroscopy. Fowler-Nordheim curves, and the turn-on and threshold fields were extracted by a diode-type tester. High uniformity, field emission efficiency and time reliability of the CN nanofibers based cathodes are good perspective for high brightness flat indicators and displays
