Title:
METHOD FOR MANUFACTURING ULTRAFINE CARBON FIBER AND FIELD EMISSION ELEMENT
Document Type and Number:
Japanese Patent JP2005060920
Kind Code:
A
Abstract:
To provide a method for manufacturing an ultrafine carbon fiber capable of controlling diameter thereof, and to provide a method for manufacturing a field emission element in which an electron emission portion is formed of an ultrafine carbon fiber and which is possible to control the density and the diameter thereof.
A size and density of a metal element or a silicide of the metal element is controlled and cohered in a crystal grain boundary of a semiconductor film, and an ultrafine carbon fiber is formed by using the metal element or the metal silicide as a core.
