Abstract
The emission properties of aligned nanotube arrays are improved by truncating the ends of the nanotubes. Truncation provides nanotubes having a height within, for example, 30% of the average truncated nanotube height, as well as ends substantially free of end caps. The cap-free ends provide desirable field concentration, and the height uniformity increases the number of participating nanotubes.
Claims16
A process for fabricating an article, comprising the steps of:
- providing an array of aligned carbon nanotubes;
- truncating at least a portion of the nanotubes, such that at least 10% of the truncated nanotubes are free of end caps.
