Abstract:
1. A method of manufacturing an electron amplifier, the method comprising the steps of: (a) forming through holes in a substrate; (b) depositing a resistive layer on the sidewalls of the through holes; (c) adding carbon nanotubes to a sol-gel solution of a material with a high secondary electron emission coefficient; (d) depositing an electron emissive layer on the resistive layer by dipping the substrate having the through holes and the resistive layer into the sol-gel solution; (e) baking the substrate on which the through holes, the resistive layer, and the electron emission layer are formed; and (f) forming an electrode layer on each of the upper and lower sides of the substrate so as to be perpendicular to the through holes.
