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 (10–102nm in diameter, and 103–104nm in length) film arrays (the pixel size:50 μm×50 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/cm2at 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.
