Electronic device having catalyst used to form carbon fiber according to Raman spectrum characteristics

摘要

A method of making an electron-emitting device has the steps of disposing a film containing metal on a substrate, arranging a plurality of catalytic particles on the film containing metal, and heat-treating the substrate on which the plurality of catalytic particles are arranged under circumstance including hydrocarbon gas and hydrogen to form a plurality of carbon fibers. Catalytic particles contain Pd and at least one element selected from the group consisting of Fe, Co, Ni, Y, Rh, Pt, La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er and Lu, and 20˜80 atm % (atomic percentage) or more of the at least one element is contained in the catalytic particles relative to Pd.
