Carbon nanotubes(CNTs) have been thought as one of the most promising coldcathode materials of electron field emitters in field emission display(FED).
The factors limiting the measurement and achievement of extremely high vacuum due to the existence of a hot cathode was overcome by the successful use of the field-emissioncoldcathode...
