Abstract

The present invention is directed towards metallized carbon nanotubes, methods for making metallized carbon nanotubes using an electroless plating technique, methods for dispensing metallized carbon nanotubes onto a substrate, and methods for aligning magnetically-active metallized carbon nanotubes. The present invention is also directed towards cold cathode field emitting materials comprising metallized carbon nanotubes, and methods of using metallized carbon nanotubes as cold cathode field emitters.

Description

Cathode device for field emission device, method for manufacturing same, and device containing same technical field The present invention relates generally to nanostructured materials, and more particularly to modified carbon nanotubes for field emission applications. Background technique Carbon nanotubes (CNTs) are currently being investigated for use as cold electron sources in various applications. These uses include displays, microwave sources, X-ray tubes, etc. For CNTs to be used as cold cathodes, they must be placed on a conductive surface (either a conductive substrate or a conductive film on a non-conductive substrate). Someone put the catalyst on the surface of the substrate and used CVD technology to grow carbon nanotubes in situ (Kimetal., J.Appl.Phys., 90(5), 2591(2001)). However, this has several drawbacks. This technique usually grows multi-walled carbon nanotubes (MWNTs), however, compared with single-walled carbon nanotubes (SWNTs), MWNTs have poor fiel...
