Title:
METHOD FOR MANUFACTURING CARBON NANOTUBES BY CATALYST, METHOD FOR MANUFACTURING ELECTRIC FIELD EMISSION ELECTRON SOURCE, ELECTRIC FIELD EMISSION ELECTRON SOURCE, AND ELECTRIC FIELD EMISSION DISPLAY
Document Type and Number:
WIPO Patent Application WO/2006/120789
Kind Code:
A1
Abstract:
This invention provides a method for manufacturing carbon nanotubes, which can accurately control conditions for the growth of carbon nanotubes for electric field emission suitable for the manufacture of electric field emission electron sources or FEDs, a method for manufacturing an electric field emission electron source, an electric field emission electron source, and an electric field emission display. In the method for manufacturing carbon nanotubes in the presence of a Co/Ti catalyst or an Fe/Al catalyst, conditions for the regulation of the thickness of a catalyst film, conditions for the regulation of the thickness of catalyst film per se, conditions for whether or not a raw material gas is preheated at a stage before the contact of the raw material gas with the catalyst film, conditions for the temperature of wall of a reaction chamber, and conditions for the regulation of the catalyst contact time of the raw material gas and the flow rate of a raw material gas are used as a group of conditions for the control of the growth of carbon nanotubes to grow the carbon nanotubes at a low temperature at or below the glass softening point. In this case, the growth can be controlled with high accuracy, and this contributes to the production of high-performance FEDs and the like.
