<p><P>PROBLEM TO BE SOLVED: To obtain an electron emitting device using carbon fibers capable of maintaining the advantages of a low electric field necessary for electron emission, a low vacuum degree necessary at the time of driving and a large amount of a resultant emission current for a long period of time. <P>SOLUTION: The method for manufacturing a plurality of the carbon fibers has a process of arranging a catalyst on a substrate and a process of heat treating the substrate on which the catalyst is arranged in an atmosphere containing carbon. The catalyst contains Pd and at least one element selected in the group consisting of Fe, Co, Ni, Y, Rh, Pt, La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er and Lu, in which 20 to 80 atm% (atomic percentage) of the selected at least one element is contained to Pd. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
