<p><P>PROBLEM TO BE SOLVED: To provide a nanocarbon material composite with a particulate protrusion structure suitable as a practical material, a method for producing the same, and an electron emission element using the nanocarbon material composite. <P>SOLUTION: The nanocarbon material composite 1 comprises a substrate 2 and a nanocarbon material 3 with a particulate protrusion structure grown on the substrate 2, wherein the particulate protrusion structure has a diameter of 50-500 nm. The nanocarbon material composite is produced through a first step of forming a thin film of palladium or a compound thereof on the substrate 2, and a second step of heating the metal thin film-bearing substrate at a temperature in a range of 550-650°C in octanol. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
