Abstract
The unique electron field emission properties of carbon nanotube films are promising for flat panel display application as the cold cathode. In this work, the multiwall carbon nanotube (10-102 nm in diameter, and 103-104 nm in length) film arrays (the pixel size: 50 μm x50 μm) were deposited on the patterned Ni-Si substrate from hydrocarbon precursor (C2H2/H2) by chemical vapor deposition at low temperature (550° C). The patterned films were characterized by scanning electron microscopy and Raman spectroscopy. The carbon nanotube film arrays exhibit good electron emission properties, e.g. low threshold emission field (below 2 V / μm), high emission current density (above 1 mA/cm2 at 10 V / μm), and high emission luminance spot density on the phosphor coated-ITO(indium tin oxide)-glass anode. These properties are good enough for high-resolution flat panel display application using carbon nanotube film arrays as the cathode.
