Traditional powder metallurgical method is used to fabricate the cold field emission cathodes. Copper powder and nano-copper oxide powder are mixed with carbon nanotubes, respectively, then pressed and sintered to form two kinds of bulk cathodes. The measurement results show that cathodes fabricated by this method have typical I-V curve and F-N curve
