Abstract
A 4.5-inch fully sealed carbon-nanotube field-emission display with a 200-m u m narrow Sap was fabricated on glass using paste squeezing and surface ru bbing techniques. The fabricated displays were fully scalable at low temper atures below 415 degrees C and showed very high luminance of 1800 cd/m(2) a t 4 V/mu m. The degradation of emission currents for single-wall carbon nan otubes was less than 10% in electrical aging tests. Large field-enhancement factors and low turn-on voltages (1.5-3 V/mu m) were attributed to well-al igned carbon nanotubes on substrates and a large number density of carbon n anotubes of 5-10/mu m(2), which was confirmed by high-resolution electron m icroscopy. Although localized states exist for various tip morphologies, wh ich was calculated by density-functional tight-binding calculations, the co ntribution from such states was found to be negligible.
